Write the ionization equation for hypochlorous acid, HClO, dissolved in water.
Pavel [41]

Answer:

HClO (l)  →  H⁺ (aq)    +       ClO⁻ (aq)

                 proton   and    hypochlorite.

Explanation:

HClO (Hypochlorous acid)

This is a weak acid that can be dissociated as this:

HClO (l)  →  H⁺ (aq)    +       ClO⁻ (aq)

                 proton   and    hypochlorite.

It is a weak acid, so it can adopt a Ka for its equilibrium

HClO +  H₂O  ⇄   H₃O⁺   +  ClO⁻          Ka
