2 Anisic acid (HC8H7O3) is found naturally in anise, a well-known culinary herb and flavouring agent. It is a monoprotic, weak acid. A 50.0 mL sample of a 0.100 M solution of anisic acid is titrated with 0.165 M potassium hydroxide (KOH). Ka for this acid = 3.39 x 10-5 .
3.2.1 Determine the pH of the anisic acid solution before the titration begins. [4]
3.2.2 What is the pH at the equivalence point? [8]
