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 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 of chloroacetic acid is 1.36 x 10⁻³.
a. H₂O
b. Na⁺
c. chloroacetate ion
d. chloroacetic acid
e. This is a buffer solution: the pH does not change upon addition of acid or base.
