$HClO_2(aq) + H_2O(l) \lt -- \gt Cl{O_2}^-(aq) + H_3O^+(aq)$

Work Step by Step

The ionization equation should describe the transfer of a proton from the acid to a water molecule, therefore, the acid and the water are the reactants, and the protonated water and the conjugate base are the products. The ionization constant expression is based on: $K_a = \frac{[Products]}{[Reactants]}$ * The water doesn't appear, because it is the solvent, and its concentration doesn't matter.
