Three flasks, labeled A, B, and C, contained aqueous solutionsof the same pH. It was known that one of the solutions was 1.0 ×10–3 M in nitric acid, one was 6 × 10–3 M in formic acid, and onewas 4 × 10–2 M in the salt formed by the weak organic base anilinewith hydrochloric acid (C6H5NH3Cl). (Formic acid ismonoprotic.)
(a) Describe a procedure for identifying the solutions.
(b) Compare qualitatively (on the basis of the precedinginformation) the strengths of nitric and formic acids with eachother and with the acid strength of the anilinium ion,
(c) Show how the information given may be used to derive valuesfor Ka for formic acid and Kb for aniline. Derive these values.
