How does adding acetate ions to an acetic acid solution affect the concentration of hydrogen ions, [H+]?

Options

  1. AIt increases [H+].
  2. BIt has no effect on[H+].
  3. CIt decreases [H+].
  4. DIt causes [H+] to become zero.

Correct answer

C. It decreases [H+].

Step-by-step solution

Adding acetate ions to an acetic acid solution decreases the concentration of hydrogen ions, [H+], by shifting the equilibrium toward undissociated acetic acid.
