In a titration of an acetic acid (CH, COOH) solution of unknown concentration, a 28.18 mL sample of the acid is required 28.73 mL of a 0.2110 mol/L KOH solution to reach the equivalence point. Determine the initial concentration of CH, COOH. What ions are present in significant concentrations in the solution at the equivalence point? Support your answer with the appropriate balanced chemical equations. What is the concentration of the conjugate base at the equivalence point? What is the percent dissociation, given an initial pH of 2.82? Determine the pH of the solution at the equivalence point.
