Asolution 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 naoh to this buffer solution causes the ph to increase slightly. the ph does not increase drastically because the naoh reacts with the present in the buffer solution. the ka of chloroacetic acid is 1.4 × 10-3. 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 naoh to this buffer solution causes the ph to increase slightly. the ph does not increase drastically because the naoh reacts with the present in the buffer solution. the ka of chloroacetic acid is 1.4 × 10-3. chloroacetic acid h2o chloroacetate this is a buffer solution: the ph does not change upon addition of acid or base. h3o+
