Question

Given the following information:

hydrocyanic acid	HCN	Ka = 4.0×10-10
hydrofluoric acid	HF	Ka = 7.2×10-4

(1) Write the net ionic equation for the reaction that occurs when equal volumes of 0.262 M aqueous hydrocyanic acid and sodium fluoride are mixed. It is not necessary to include states such as (aq) or (s).

(2) At equilibrium will the products or the reactants be favored?

(3) Will the pH of the solution be less than, more than, or equal to 7
