The pH of a solution describes the concentration of H+ in a solution, where pH = -log[H+]. Note that this is a log10, not the natural log, so the inverse is [H+] = 10-pH. Acetic acid dissociates in water according to the following reaction:
-+CH3COOH (aq) ⇄ CH3COO (aq) + H (aq)
The pH of a 1.0 M solution of acetic acid is 2.37. What is the value of the equilibrium constant for the dissociation of acetic acid?
