Question

Equal volumes of 0.276 M aqueous solutions of benzoic acid (C₆H₅COOH(aq)) and sodium nitrite (NaNO₂) are mixed.

(1) Write the net ionic equation for the overall reaction that takes place as the system comes to equilibrium.

Write acetic acid, benzoic acid or formic acid and their conjugates in the form RCOOH / RCOO^-. For example, benzoic acid should be written "C₆H₅COOH" NOT "C₆H₅CO₂H". It is not necessary to include states such as (aq).

(2) What is the value of the equilibrium constant for this reaction?

(3) What is the pH of the resulting solution?
