An aqueous solution of acetic acid is found to have
the following equilibrium concentrations at 25 °C:
[CH3COOH] = 1.65 x 10-2 M; [H+] = 5.44 x 10-4 M; and
[CH3COO-] = 5.44 * 10-4 M. Calculate the equilibrium
constant Kc for the ionization of acetic acid at 25 °C. The
reaction is
CH3COOH(aq) ⇌ H+(aq) + CH3COO-(aq)
