WebpKa = – log 10 [Ka] We can determine whether an acid is a strong acid or a weak acid by looking at its pKa value. The acid is weak if the pKa value is high. Because a greater pKa number suggests that Ka is low, this is the case. The value of [A – ] [H +] should be lower than the value of [HA] in order for Ka to be low.
