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. In organic synthesis, HClO converts alkenes to chlorohydrins. In biology, hypochlorous acid is generated in activated neutrophils by myeloperoxidase-mediated peroxidation of chloride ions, and contributes to the destruction of bacteria. In medicine, hypochlorous acid water has been used as a disinfectant … Meer weergeven Hypochlorous acid (ClOH, HClO, HOCl, or ClHO ) is a weak acid that forms when chlorine dissolves in water, and itself partially dissociates, forming hypochlorite, ClO .
