Three flasks, labeled A, B, and C, contained aqueous solutions of 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 one was 4 × 10–2 M in the salt formed by the weak organic base aniline with hydrochloric acid (C6H5NH3Cl). (Formic acid is monoprotic.)

(a) Describe a procedure for identifying the solutions.

(b) Compare qualitatively (on the basis of the preceding information) the strengths of nitric and formic acids with each other and with the acid strength of the anilinium ion,

(c) Show how the information given may be used to derive values for Ka for formic acid and Kb for aniline. Derive these values.
