1) Barium sulfate, BaSO4 is a salt that is formed by a strong base Ba (OH) 2 and a strong acid H2SO4. Does not undergo hydrolysis. pH = 7 (neutral solution medium).
2) Ammonium chloride, NH4Cl is a salt that is formed by a weak base NH4OH and a strong acid HCl. Undergoes hydrolysis by cation:
NH4 + + H2O = NH4OH + H +
pH <7 (acidic solution).
3) Sodium acetate, CH3COONa is a salt that is formed by a strong base NaOH and a weak acid CH3COOH. Undergoes hydrolysis by anion:
CH3COO- + H2O = CH3COOH + OH-
pH> 7 (alkaline solution).
