What is the principal form of benzoic acid at pH 8.2 if the pKa value is 4.2 correct answer: So, at pH 4.20, there is a 1:1 mixture of benzoic acid (HA) and benzoate ion (A-). At pH = pKa + 1 (= 5.20), the quotient [A-]/[HA] is 10:1. At pKa + 2 (= 6.20), the quotient [A-]/[HA] is 100:1. As pH increases, all the way to pKa + 4 the [A-]/[HA] is 10000:1 *The predominant form of benzoic acid at pH 8 is the benzoate anion For a monoprotic system, the species ___ is the predominant form when ...
