Question

A solution is prepared by dissolving 0.23 moles of chloroacetic acid and 0.27 moles of

sodium chloroacetate in water sufficient to yield 1.00 L of solution. The addition of 0.05 mole of

HCl to this buffer solution causes the pH to drop slightly. The pH does not decrease drastically

because the HCl reacts with the __________ present in the buffer solution. The Ka of

chloroacetic acid is 1.36 × 10​
