We can use the relative strengths of acids and bases to predict the direction of an acidbase reaction by following a single rule: an acidbase equilibrium always favors the side with the weaker acid and base, as indicated by these arrows: \[\text{stronger acid + stronger base} \ce{ <=>>} \text{weaker acid + weaker base} \nonumber \]. concentration or input concentration to calculate for density. A. Hi Ryan, For a 25% v/v nitric acid solution you will need 130/4 = 32.5 litres of acid. Garlic. Because percent solutions can be expressed in three different ways, it is imperative that the type of percent solution be explicitly stated. The solution dilution calculator tool calculates the volume of stock concentrate to add to achieve a specified volume and concentration. Once again, the activity of water has a value of 1, so water does not appear in the equilibrium constant expression. Nitric acid is the most commonly used wash for scale removal and pH stabilization after a caustic wash. At a typical concentration of 0.5%, it can be used effectively at lower temperatures than caustic solutions, requiring less heating. There are some exceptions, such as carbon monoxide, CO, nitrous oxide, N2O, and nitric oxide, NO. Hydrofluoric acid is particularly dangerous because it is capable of eating through glass, as seen in the video in the links sectionV1. A standard acid-base titration uses a titrant of known concentration to titrate a tank of unknown concentration. Name. Your Safer Source for Science. HCl. Like all equilibrium constants, acid-base ionization constants are actually measured in terms of the activities of H + or OH , thus making them unitless. But when mixing a chemical solution, you can determine the expected pH using . Legal. 2. The polarity of the H-A bond affects its acid strength. pH is 3.00. National Library of Medicine. Cl-Chloride. H 2 SO 4. Once you realize there are two sodium ions per carbonate ion, the problem is simple: N = 0.321 g Na 2 CO 3 x (1 mol/105.99 g) x (2 eq/1 mol) N = 0.1886 eq/0.2500 L. N = 0.0755 N. Hence the ionization equilibrium lies virtually all the way to the right, as represented by a single arrow: \[HCl_{(aq)} + H_2O_{(l)} \rightarrow H_3O^+_{(aq)}+Cl^_{(aq)} \label{16.5.17} \]. The Complete Aqueous Nitric Acid Solutions Density-Concentration Calculator. oxyacid, any oxygen-containing acid. Input a temperature and density within the range of the table to calculate for concentration or input concentration . As noted above, weight refers to mass (i.e., measured on a balance). Representative value, w/w %. Hence, the acid is strong. Then refer to Tables \(\PageIndex{1}\)and\(\PageIndex{2}\) and Figure \(\PageIndex{2}\) to determine which is the stronger acid and base. Conversely, smaller values of \(pK_b\) correspond to larger base ionization constants and hence stronger bases. For example, hydrofluoric acid is a weak acid1, but it is extremely dangerous and should be handled with great care. For example, the general equation for the ionization of a weak acid in water, where HA is the parent acid and A is its conjugate base, is as follows: \[HA_{(aq)}+H_2O_{(l)} \rightleftharpoons H_3O^+_{(aq)}+A^_{(aq)} \label{16.5.1} \]. Upon distillation, nitric acid in its pure form begins to boil at 78.2C and becomes solid when it is well cooled. The \(HSO_4^\) ion is also a very weak base (\(pK_a\) of \(H_2SO_4\) = 2.0, \(pK_b\) of \(HSO_4^ = 14 (2.0) = 16\)), which is consistent with what we expect for the conjugate base of a strong acid. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. H 2 SO 4 + 2NaOH Na 2 SO 4 + 2H 2 O. sulfuric acid reacts with sodium hydroxide on the 1:2 basis. The conjugate acidbase pairs are listed in order (from top to bottom) of increasing acid strength, which corresponds to decreasing values of \(pK_a\). For example, when using a strong acid and a weak base, an indicator that changes at a low pH is needed, such as methyl orange (3.1-4.4). Initial Data. u Assumes about one-third of acid is effective since phosphoric acid does not completely dissociate. (In fact, the \(pK_a\) of propionic acid is 4.87, compared to 4.76 for acetic acid, which makes propionic acid a slightly weaker acid than acetic acid.) This works for a 10ml vat sample titrated with 1.0N sodium Hydroxide, and give you a result expressed as percent by volume of 70% (700g/l0 nitric acid. Battery acid electrolyte is recommended by some and is about 35% strength. Acid Strength Definition. Equivalence point means the point during titration at which the titrant added has completely neutralized the analyte solution. Concentration Before Dilution (C1) %. Predict its pH when it is diluted to 0.1 g/dm 3 . Acid strength can be defined as the tendency of an acid, to dissociate into a proton, H+, and an anion, A, and symbolized by the formula HA. All acidbase equilibria favor the side with the weaker acid and base. Consequently, aqueous solutions of acetic acid contain mostly acetic acid molecules in equilibrium with a small concentration of \(H_3O^+\) and acetate ions, and the ionization equilibrium lies far to the left, as represented by these arrows: \[ \ce{ CH_3CO_2H_{(aq)} + H_2O_{(l)} <<=> H_3O^+_{(aq)} + CH_3CO_{2(aq)}^- } \nonumber \]. They are also highly resistant to temperature changes. Nitric Acid | HNO3 | CID 944 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. University of Maiduguri. You have added 49.00 10-3 L 0.100 M NaOH = 4.90 10-3 moles of OH- ions. In a weak acid like hydrofluoric acid (HF), not all of the HF molecules split up, and although there will be some H+ and F- ions released, there will still be HF molecules in solution1. b) How many moles of sulfuric acid (H 2SO 4) are required to produce 2.0 moles of iodine (I 2) Conversion factor: Mole ratio between the unknown substance (sulfuric acid) and the known substance (iodine): 7 mol H 2SO 4 3 mol l 2 7 mol H 2SO 4 3 mol l 2 2.0 mol l 2 = 4.7 mol H 2SO 4 7 Mole - mass calculations A balanced chemical equation This tells us that there is a nitric acid solution of 65% w/v. When different volumes of an identical solution are added together, the final volume will always be exactly the sum of the individual portions added. H 2 O. This article will provide you with the molarity definition and the molarity formula.. To understand the topic as a whole, you will want to learn the mole . According to Tables \(\PageIndex{1}\) and \(\PageIndex{2}\), \(NH_4^+\) is a stronger acid (\(pK_a = 9.25\)) than \(HPO_4^{2}\) (pKa = 12.32), and \(PO_4^{3}\) is a stronger base (\(pK_b = 1.68\)) than \(NH_3\) (\(pK_b = 4.75\)). The table was taken from "Perry's Chemical Engineers' Handbook" by Robert H. Perry, Don Green, Sixth Edition. pH Calculator. Although exact determination is impossible, titration is a valuable tool for finding the molarity. HO 2 C . [3] White fuming nitric acid, also called 100% nitric acid or WFNA, is very close to anhydrous nitric acid. Stephen Lower, Professor Emeritus (Simon Fraser U.) Calculate the molality of nitric acid solution a) 29.0 b) 11.0 c) 43.2 d) 16.0 Question 8 (10 points) A concentrated aqueous solution of nitric acid (HNO3) has a density . Use the relationships pK = log K and K = 10pK (Equations \(\ref{16.5.11}\) and \(\ref{16.5.13}\)) to convert between \(K_a\) and \(pK_a\) or \(K_b\) and \(pK_b\). The titration curve can also determine whether the solution is a strong or weak acid/base. For weak acids and bases, the higher the Ka or Kb, the more acidic or basic the solution. Calculate \(K_a\) for lactic acid and \(pK_b\) and \(K_b\) for the lactate ion. Partial List of Strong Acids: Hydrochlroic acid (HCl), Nitric Acid (HNO3), Perchloric Acid (HClO4), Sulfuric Acid (H2SO4), Partial List of Strong Bases: Sodium Hydroxide (NaOH), Barium Hydroxide (Ba(OH)2), Calcium Hydroxide (Ca(OH)2), Lithium Hydroxide (LiOH) (Hydroxides of Group I and II elements are generally strong bases), Partial List of Weak Acids: Acetic Acid (CH3COOH), Carbonic Acid (H2CO3), Phosphoric Acid (H3PO4), Partial List of Weak Bases: Ammonia (NH3), Calcium Carbonate (CaCO3), Sodium Acetate (NaCH3COO). The same goes for strong bases, except the negative logarithm gives you the pOH as opposed to the pH. For this reason, you must select the correct indicator for the right combination of solutions, as the range of color changes needs to have the equivalence point in it. Each calculator cell shown below corresponds to a term in the formula presented above. Likewise nitric acid, HNO 3, or O 2 NOH (N oxidation number = +5), . The molecular weight of HCl is 36.47 g/mol. PH is based on the concentration of the hydronium ion (H3O+) which is a product of the reaction of acid and water. For example, hydrochloric acid (HCl) is a strong acid. Check out 19 similar mixtures and solutions calculators , Table of common acids and bases and their strengths. Butyric acid is responsible for the foul smell of rancid butter. Sulfuric acid. In Imperial or US customary measurement system, the density is equal to 94.44726 pound per cubic foot [lb/ft], or 0. . So, in 20 ml of acidic solution 1.80 x 10-3 equivalent of acids. Place on a white tile under the burette to better observe the color. Consider, for example, the \(HSO_4^/ SO_4^{2}\) conjugate acidbase pair. If the circuit is completed by a solution containing large numbers of molecules and either no ions or few ions, the solution does not conduct or conducts very weakly as shown for acetic acid. The main industrial use of nitric acid is for the production of fertilizers. The titration calculations for NaOH: For 20 ml acid solution: 15 ml 0.12 mol NaOH required. All-In-One Science Solution. Just like water, HSO4 can therefore act as either an acid or a base, depending on whether the other reactant is a stronger acid or a stronger base. If we are given any one of these four quantities for an acid or a base (\(K_a\), \(pK_a\), \(K_b\), or \(pK_b\)), we can calculate the other three. Because the \(pK_a\) value cited is for a temperature of 25C, we can use Equation \(\ref{16.5.16}\): \(pK_a\) + \(pK_b\) = pKw = 14.00. * An acid that has a very low pH (0-4) are known as Strong acids. The H+ concentration is 1.0 10-4/(0.049 L + 0.050 L) = 1.0 10-4/(0.099 L) = 1.00 10-3 M. As pH = -log[H+], pH will be 3. However, when mixing miscible liquids (such as water and ethanol), the final volume of solution is not exactly equal to the sum of the individual volumes. The usual molar ratio between concentrated hydrochloric acid and concentrated nitric acid is HCl:HNO 3 of 3:1. So, the number of base equivalents = 12 15 = 1.8 10-3 equivalent. Keep in mind, concentrated HCl is about 35%, while concentrated HNO 3 is about 65%, so the volume ratio is usually 4 parts concentrated hydrochloric acid to 1 part concentrated nitric acid. The equivalence point will occur at a pH within the pH range of the stronger solution, i.e., for a strong acid and a weak base, the pH will be <7. One method is to use a solvent such as anhydrous acetic acid. 0.5 X 100 = 69 X q. q= 50/69 = 0.7246 ml. Asked for: corresponding \(K_b\) and \(pK_b\), \(K_a\) and \(pK_a\). PubChem . It should take approximately 25 minutes. Nitric acid is a highly corrosive mineral acid and is commonly used as a strong oxidizing agent. Acidbase reactions always proceed in the direction that produces the weaker acidbase pair. Nitric acid (HNO) is a colorless liquid with yellow or red fumes with an acrid odor. This test method is suitable for concentrations between approximately 50 and 70 %, calculated as nitric acid. The curve around the equivalence point will be relatively steep and smooth when working with a strong acid and a strong base. Recall from Chapter 4 that the acidic proton in virtually all oxoacids is bonded to one of the oxygen atoms of the oxoanion. The Ka value of ammonium (NH4+) is 5.6*10-10, the Kb value of ammonia (NH3) 1.8*10-5, is ammonium more strongly acidic than ammonia is basic? Thus, solution mass is the combined mass of solute and solvent, and solution volume is the combined volume of solute . pH of Common Acids and Bases. When the color change becomes slow, start adding the titrant dropwise. For example, adding 50 mL of water to 50 mL of water will result in a total volume of 100 mL, and adding 75 mL of 100% ethanol to 75 mL of 100% ethanol will result in a total volume of 150 mL. There are two different nitric acid production methods: weak nitric acid and high-strength nitric acid. Acid & Base Molarity & Normality Calculator . The Ka value is a measure of the ratio between reactants and products at equilibrium. For a polyprotic acid, acid strength decreases and the \(pK_a\) increases with the sequential loss of each proton. Weak bases react with water to produce the hydroxide ion, as shown in the following general equation, where B is the parent base and BH+ is its conjugate acid: \[B_{(aq)}+H_2O_{(l)} \rightleftharpoons BH^+_{(aq)}+OH^_{(aq)} \label{16.5.4} \]. Nitric acid is the inorganic compound with the formula H N O 3. The LibreTexts libraries arePowered by NICE CXone Expertand are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. Equilibrium always favors the formation of the weaker acidbase pair. To convert mass to moles, we need the molecular weight. The larger the Ka, the stronger the acid and the higher the H + concentration at equilibrium. Acid. The selection of the indicator used depends on the initial concentration of the Nitric Acid and the strength of the alkali used. It is both extremely corrosive and toxic. For an aqueous solution of a weak acid, the dissociation constant is called the acid ionization constant (\(K_a\)). Example: Sodium chloride (1 + 19) Dissolved in 19 weight of water with respect to 1 of NaCl. HCL, 37% - 12.2 Molar Strength = 36.5-38%, Density = 1.185, Molecular Weight = 36.5 . The instructor will test the conductivity of various solutions with a light bulb apparatus. So 1 US gallon = 3.78 litres, Then 130 x 3.78 = 491 litres of liquid volume. The Ka value for acetic acid is 1.76*10-5, and the Ka value for benzoic acid is 6.46*10-5, if two solutions are made, one from each acid, with equal concentrations, which one will have the lower pH? { Acid_and_Base_Strength : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Calculating_A_Ka_Value_From_A_Measured_Ph : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Calculating_Equilibrium_Concentrations : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Fundamentals_of_Ionization_Constants : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Weak_Acids_and_Bases : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Weak_Acids_and_Bases_1 : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, { Acid : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Acids_and_Bases_in_Aqueous_Solutions : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Acid_and_Base_Indicators : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Acid_Base_Reactions : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Acid_Base_Titrations : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Buffers : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Buffers_II : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Ionization_Constants : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Monoprotic_Versus_Polyprotic_Acids_And_Bases : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, [ "article:topic", "acid strength", "base strength", "showtoc:no", "license:ccbyncsa", "licenseversion:40" ], https://chem.libretexts.org/@app/auth/3/login?returnto=https%3A%2F%2Fchem.libretexts.org%2FBookshelves%2FPhysical_and_Theoretical_Chemistry_Textbook_Maps%2FSupplemental_Modules_(Physical_and_Theoretical_Chemistry)%2FAcids_and_Bases%2FIonization_Constants%2FAcid_and_Base_Strength, \( \newcommand{\vecs}[1]{\overset { \scriptstyle \rightharpoonup} {\mathbf{#1}}}\) \( \newcommand{\vecd}[1]{\overset{-\!-\!\rightharpoonup}{\vphantom{a}\smash{#1}}} \)\(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\) \(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\)\(\newcommand{\AA}{\unicode[.8,0]{x212B}}\), Demonstration of Acid and Base Conductivity, status page at https://status.libretexts.org. of the nitric acid of the given purity (65%) and add to distilled water in a standard flask (1L) up to mark . process called interpolation. Your Safer Source for Science. Phosphoric acid is sometimes used but is somewhat less common. One specication for white fuming nitric acid is that it has a maximum of 2% . The equilibrium will therefore lie to the right, favoring the formation of the weaker acidbase pair: \[ \underset{\text{stronger acid}}{CH_3CH_2CO_2H_{(aq)}} + \underset{\text{stronger base}}{CN^-_{(aq)}} \ce{<=>>} \underset{\text{weaker base}}{CH_3CH_2CO^-_{2(aq)}} +\underset{\text{weaker acid}} {HCN_{(aq)}} \nonumber \], A Video Discussing Polyprotic Acids: Polyprotic Acids [youtu.be]. Enter appropriate values in all cells except the one you wish to calculate. When examining the equation for each of the percent solutions above, it is very important to note that in all cases the denominator refers to the solution mass or volume and not just the solvent mass or volume. Similarly, Equation \(\ref{16.5.10}\), which expresses the relationship between \(K_a\) and \(K_b\), can be written in logarithmic form as follows: The values of \(pK_a\) and \(pK_b\) are given for several common acids and bases in Tables \(\PageIndex{1}\) and \(\PageIndex{2}\), respectively, and a more extensive set of data is provided in Tables E1 and E2. Chemistry questions and answers. This would be a simple mass particle and let me go get my mona math of nitric, acid, nitric acid, which will be 484959 plus 63. Introduction Again. Because \(pK_a\) = log \(K_a\), we have \(pK_a = \log(1.9 \times 10^{11}) = 10.72\). To solve this problem, you need to know the formula for sodium carbonate. Polyprotic acids (and bases) lose (and gain) protons in a stepwise manner, with the fully protonated species being the strongest acid and the fully deprotonated species the strongest base. If you have problems or comments concerning our WWW service, please send an e-mail to webmaster. As you may know, when an acid or a base dissolves in water, their H+\small\text{H}^+H+ and OH\small\text{OH}^-OH ions respectively dissociate, shifting the natural self-ionization equilibrium of water (2H2OH3O++OH\small2\text{H}_2\text{O}\rightleftharpoons\text{H}_3\text{O}^+ + \text{OH}^-2H2OH3O++OH), making the solution more acidic or more basic. 16.4: Acid Strength and the Acid Dissociation Constant (Ka) is shared under a CC BY-NC-SA 4.0 license and was authored, remixed, and/or curated by LibreTexts. home; aqion; about; Add 1, 2 or 3 reactants to water: . Make sure not to pour the solution above your head and to remove the funnel after you have finished pouring. Similarly, the equilibrium constant for the reaction of a weak base with water is the base ionization constant (\(K_b\)). w Phosphoric acid comes in many strengths, but 75% is most common. Conversely, smaller values of \(pK_b\) correspond to larger base ionization constants and hence stronger bases. Start adding the titrant slowly, swirling the Erlenmeyer flask constantly. Thus the proton is bound to the stronger base. The dissociation of a robust acid in solution is effectively complete, except in its most concentrated solutions. Titration is a method to determine the unknown concentration of a specific substance (analyte) dissolved in a sample of known concentration. Each acid and each base has an associated ionization constant that corresponds to its acid or base strength. The behavior for a 20% nitric acid concentration is almost the same, the difference being that NC shows a higher weight loss. Knowing the density of the acid to be 1.413 g/mL, we can calculate the weight of 1 L of 70% HNO 3 to be 1413 Ka. Hydronium ion H3O+ H2O 1 0.0 The strength of an acid or base can be either strong or weak. Instead, a pH meter is often used. This calculator calculates for concentration or density values that are between those given in the table below by a Acid and Base pH Indicators - pH range vs. color change for acid and base indicators - together with pKa and structures of the indicators. You can also calculate the mass of a substance needed to achieve a desired molarity. We could also have converted \(K_b\) to \(pK_b\) to obtain the same answer: \[pK_b=\log(5.4 \times 10^{4})=3.27 \nonumber \], \[K_a=10^{pK_a}=10^{10.73}=1.9 \times 10^{11} \nonumber \]. Because acetic acid is a stronger acid than water, it must also be a weaker base, with a lesser tendency to accept a proton than \(H_2O\). Nitric acid or citric acid (CitriSurf) immersion bath to fully dissolve any free irons and sulfides and expedite the formation of passive film or oxide layer Water rinse - Commonly with DI water in high-precision industries Second water rinse - Commonly with DI Water in high-precision industries Dry parts National Center for Biotechnology Information. For example, if the percent solution under consideration is to be used at widely different temperatures, then it is better to prepare the solution as a weight/weight % solution because its concentration would be independent of variations in ambient temperature. The table below gives the density (kg/L) and the corresponding The volume of 100 grams of Nitric acid is 70.771 ml. Dilution Factor Calculator - Molarity, Percent. In presence of strong acids like sulfuric acid, HNO 3 acts as the base because it has to accept the proton from the stronger acid. The larger the \(K_b\), the stronger the base and the higher the \(OH^\) concentration at equilibrium. It is then easy to see why French chemist Joesph Louis Gay-Lussac first used the term when performing early experiments into the atomic composition of materials (he would later go on to improve the burette and invent the pipette). Weak acids and bases are molecules that do not fully dissociate when in solution; that is, they are not salts. Add the indicator to the flask. In particular, we would expect the \(pK_a\) of propionic acid to be similar in magnitude to the \(pK_a\) of acetic acid. Then it remains 5.00 10-3 - (4.90 10-3) = 1.0 10-4 moles H+. v 93% sulfuric acid is also known as 66 be' (Baume') acid. Enter both the weight and total volume of your application above if the chemical is a solid. The \(pK_a\) of butyric acid at 25C is 4.83. The blue line is the curve, while the red line is its derivative. CALCULATOR OPTIONS Acid & Base Molarity & Normality Calculator. Here, we have used, As noted above, weight refers to mass (i.e., measured on a balance). Each sensor, manufactured in Finland, is pressure and temperature tested as part of the production process to ensure they meet our highest standards. 4. (@37.5%) = 12.2 moles (range 11.85 - 12.34) Boiling Point 110C (230F) Nitric Acid. * A base that has a very high pH (10-14) are known as .
