Question
A solution is prepared by dissolving 0.23 mol of chloroacetic acid and 0.27 mol of sodium chloroacetate in water sufficient to yield 1.00 L of solution. The addition of 0.05 mol of HCI to this buffer solution causes the pH to drop slightly. The pH does not decrease drastically because the HCI reacts with the present in the buffer solution. The K_a of chloroacetic acid is 1.36 times 10^-3. H_2 O Na^+ chloroacetate ion chloroacetic acid This is a buffer solution: the pH does not change upon addition of acid or base.Explanation / Answer
ClCH2COOH <----> ClCH2COO- + H+
HCl -------> Cl- + H+
The H+ ions from added HCl reacts with Chloroacetate ions and more amount of Chlkoroacetic acid will be formed due to common ion effect.
