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 â Ac^- + Na⁺, for instance: CH₃COONa â CH₃COO^- + Na⁺

2. the hydrolysis of the water

Ac^- + H₂O â AcH + OH^-, for example: CH₃COO^- + H₂O â CH₃COOH + OH^-

knowing that the initial concentration of the salt is 0.17 M and the acid dissociation constant, K_a , is 1.08e-7.

pH=?
