Calculate the pH of a solution containing a salt AcNa derived from a strong base (NaOH) and a weak acid (AcH), like CH3COONa, KF, NaNO2 and so on. In this case two processes have to be considered: 1. Dissociation of the salt, within the assumption that the salt is a strong electrolyte:      AcNa → Ac- + Na+,   for instance: CH3COONa → CH3COO- + Na+ 2. the hydrolysis of the water      Ac- + H2O ⇌ AcH + OH-,    for example: CH3COO- + H2O ⇌ CH3COOH + OH- knowing that the initial concentration of the salt is 1.6 M and the acid dissociation constant, Ka , is 1.38e-10
