Acetate butler is often used as a buffer solution for protein studies at acidic pH (from 3.6 to 5.6). The dissociation reaction is: CH_3COOH doubleheadarrow CH_3COO^- + H^+ Here CH_3COOH (abbreviated as HOAc) and the acetate anion CH_3COO^-(abbreviated as OAc^+) are the conjugate acid-base pair. Suppose you prepared an acetate buffer containing 0.1 M of HOAc and 0.1 M of OAc-. What are the [H^+] and pH of this solution? Now you add 0.01M HCl to your acetate buffer. What are the [H^+] and the pH after the HCl is added and the mixture reaches equilibrium? Suppose you add 0.01 M HCl to a solution containing 0.18 M of HOAc and 0.02 M of OAc^-. What are the [H^+] and the pH before the HCl is added, and after the HCl is added? Suppose you add 0.01 M HCl to a solution containing 0.02 M of HOAc and 0.18 M of OAc^-. What are the [H^+] and the pH before the HCl is added, and after the HCl is added?
