Highest pka
WebFor example, the Ka constant for acetic acid (CH 3 COOH) is 0.0000158 (= 10 -4.8 ), but the pKa constant is 4.8, which is a simpler expression. In addition, the smaller the pKa value, the stronger the acid. For example, the pKa value of lactic acid is about 3.8, so that means lactic acid is a stronger acid than acetic acid.
