To calculate the pH of the reaction, we use the equation: The chemical equation for the dissociation of nitric acid follows: By stoichiometry of the reaction: 1 mole of nitric acid produces 1 mole of hydrogen ions and 1 mole of nitrate ions. So, Putting values in above equation, we get: Hence, the pH of the solution is 0.125 Study with Quizlet and memorize flashcards containing terms like Calculate pH - addition of 250cm3 of water to 50cm3 of 0.200 mol dm-3 HNO3, Calculate pH - addition of 25cm3 of water to 100cm3 of 0.100 mol dm-3 H2SO4, Calculate pH of 10g dm-3 HCl and more.

The pH calculator tool provides expected pH values for a variety of common laboratory and industrial chemicals. Find expected pH for a given concentration simply by entering the molarity or enter weight and total volume. You can even calculate the impact of dilution, entering starting molarity and final volume.
