Acetic acid (HCH3CO0 or CH3COOH) is a weak acid with a Ka = 1.80 x 105. Sodium acetate (NaCH3COO or CH;COONA) is a salt (ionic compound) that will dissociate completely in water to produce Na* and acetate ion (CH3CO0). What is the pH of a solution of a 0.305M solution of acetic acid that also contains 0.500M sodium acetate? (Hint: check to see if the amount of acid that dissociates is insignificant in comparison with the starting concentration of acid and the amount of acetate ion)
