WebHydrolysis and Buffers. Purpose: Test pH of solutions and then calculate initial concentrations of species involved. If the salt of a weak acid and a strong base, such as sodium acetate, is dissolved in water, an acid-base reaction involving the anion of the weak acid will occur to generate the acid and hydroxide ion. 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).
