WebSalt hydrolysis is an important component of acid-base reactions, if the ion comes from a weak acid or base, that ion can act as the conjugate of the weak acid or base. For each of the four salts given in the lab, predict if the pH will be acidic, basic, or neutral for a 0.1 M aqueous solution for each salt. WebIV. Buffers A buffer is a solution composed of a weak acid (HA) and the salt of that weak acid (i.e., the conjugate base, A-), or a weak base (B) and the salt of that weak base (i.e., the conjugate acid BH+) Buffer systems resist large pH changes because added acids or bases are neutralized by the existing HA/A-system (equilibrium).
