Answers
Acetic Acid(HOAc) + Sodium Acetate(NaOAc) => common ion solution that inhibits changes in pH with addition of quantities of H^+ or OH^-. If H^+ is added to the buffer solution, the excess reacts with the OAc^- ion to form HOAc and consumes the excess H^+. If OH^- is added, the OH^- ions combine with H^+ forming water and consumes the excess OH^-.
