3 H2SO4 + 2 Fe(OH)2 + KClO → 5 H2O + KCl + Fe2(SO4)3
This is an acid-base reaction (neutralization): H2SO4 is an acid, Fe(OH)2 is a base.
This is an oxidation-reduction (redox) reaction:
ClI + 2 e- → Cl-I (reduction)
2 FeII - 2 e- → 2 FeIII (oxidation)
KClO is an oxidizing agent, Fe(OH)2 is a reducing agent.
