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). WebHypochlorous acid is the first product formed when chlorine gas is added to water. Both its toxicity to aquatic organisms and the rate at which it forms subsequent reaction products …

"WebSmaller 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 acid–base pair. " - Ionization of hypochlorous acid in water
