SO2 + H2O → HSO3– + H+

Reason: ionization is the formation of ions from neutral molecules (or acids reacting with water). The SO2 + H2O reaction produces ions (HSO3– and H+). C + O2 → CO2 is a redox/combination reaction, H2CO3 → H2O + CO2 is decomposition, and Mg(OH)2 → Mg2+ + 2OH– is best described as dissociation of an ionic solid.
