Question

(1)

Given the following information:

hydrocyanic acid	HCN	Ka = 4.0×10-10
diethylamine	(C2H5)2NH	Kb = 6.9×10-4

(1) Write the net ionic equation for the reaction that occurs when equal volumes of 0.152 M aqueous hydrocyanic acid and diethylamine are mixed. It is not necessary to include states such as (aq) or (s).

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

(3) Will the pH of the resulting solution be greater than, less than, or roughly equal to 7?

(2)

Given the following information:

acetic acid	CH3COOH	Ka = 1.8×10-5
diethylamine	(C2H5)2NH	Kb = 6.9×10-4

(1) Write the net ionic equation for the reaction that occurs when equal volumes of 0.289 M aqueous acetic acid and diethylamine are mixed. It is not necessary to include states such as (aq) or (s).

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

(3) Will the pH of the resulting solution be greater than, less than, or roughly equal to 7?
