Question 1

Benzoic acid (C6H5CO2H = HBz) solutions are sometimes used in experiments to determine the molarity of a basic solution of unknown concentration. What is the pH of a 0.100 M solution of benzoic acid if Ka = 6.5 × 10-5 and the equilibrium equation of interest is HBz(aq) + H2O(l) ⇌ H3O+(aq) + Bz-(aq).

Question 2

Potassium hydrogen phthalate (molar mass = 204.2 g/mol) is one of the most commonly used acids for standardizing solutions containing bases. KHP is a monoprotic weak acid with Ka = 3.91 × 10-6. Calculate the pH of the solution that results when 0.40 g of KHP is dissolved in enough water to produce 25.0 mL of solution.
