Question: A buffered solution contains 0.50 M acetic acid (HC 2 H 3 O 2 , K a = 1.8 10 5 ) and 0.50

A buffered solution contains 0.50 M acetic acid (HC₂H₃O₂, K_a = 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.
