Question:

A buffered solution contains 0.50 M acetic acid (HC2H3O2, Ka = 1.8 × 10–5) and 0.50 M sodium acetate (NaC2H3O2).

a. Calculate the pH of this solution.

b. Calculate the change in pH that occurs when 0.010 mol of solid NaOH is added to 1.0 L of the buffered solution. Compare this pH change with the change that occurs when 0.010 mol of solid NaOH is added to 1.0 L of water.
