Suppose your colleague was relying on receiving your purified product in order to prepare a dilute aqueous standard solution of benzoic acid e.g. for a titration. She takes 160 mg of your benzoic acid and dissolves it in just enough water so the solution exactly fills a 250 mL volumetric flask. Given that the acid dissociation constant of benzoic acid Ka = 6.3 x 10-5, calculate the pH of her resulting solution.
