Since Ka of acetic acid > Ka of hypochlorous acid, there will be more molecules of acetic acid than hypochlorous acid (more ions in solution). Acetic acid is a stronger acid than hypochlorous acid. The pKa of acetic acid is 4.8, and the pKa of hypochlorous acid is 7.5. The acid with the lower pKa value is the stronger acid. (acid/base equilibria)
