Web28 apr. 2024 · Smaller values of \(pK_a\) correspond to larger acid ionization constants and hence stronger acids. Conversely, smaller values of \(pK_b\) correspond to larger base ionization constants and hence stronger bases. At 25°C, \(pK_a + pK_b = 14.00\). Acid–base reactions always proceed in the direction that produces the weaker … WebThe degree of dissociation of hypochlorous acid is pH dependent being gradually suppressed as the pH falls. At a pH < 5.0 then approximately 100% of the chlorine is in HOCl form which falls to 50% at pH 7.5, while at pH > 9.0 100% of chlorine is present as OCl (Table 31.2).
