Br2 (aq) + 2 FeSO4 (aq) + H2SO4 (aq) → Fe2(SO4)3 (s) + 2 HBr (aq)
This is an oxidation-reduction (redox) reaction:
2 Br0 + 2 e- → 2 Br-I (reduction)
2 FeII - 2 e- → 2 FeIII (oxidation)
Br2 is an oxidizing agent, FeSO4 is a reducing agent.
This is a precipitation reaction: Fe2(SO4)3 is the formed precipitate.
