What happens when HCI is added to a buffer composed of CH3COOH and CH3COO™? (A) There is no reaction because CH3COO and CH3COO- form a buffer. (B) The HCI reacts with CH3COO- converting some of it into CH3COOH. (C) The HCI reacts with CH3COOH converting some of it into CH3COO-. (D) The HCI is neutralized and all concentrations (CH3COOH and CH3COO-) remain unchanged. (E) Ka for acetic acid goes down.
