WebSince log 1 = 0, then, clearly, in this situation, [Ionised acid] = [unionised acid] This implies that, wherever the sum of pH = PK, then, exactly 50% of the drug dissociates. Additionally, when drug is acidic, the fall in the pH of the medium, yields a relatively greater amount of unionised acid. WebA weak acid’s pH will be higher than a strong acid’s pH at the same concentration. In a solution of strong acid, the molecules are fully ionised. In a weak acid, few of the …
