2 FeO (s) + 4 H2SO4 (aq) → Fe2(SO4)3 (s) + SO2 (aq) + 4 H2O (l)
This is an acid-base reaction (neutralization): FeO is a base, H2SO4 is an acid.
This is an oxidation-reduction (redox) reaction:
SVI + 2 e- → SIV (reduction)
2 FeII - 2 e- → 2 FeIII (oxidation)
H2SO4 is an oxidizing agent, FeO is a reducing agent.
