1) Iron reacts with chlorine, we get iron (II) chloride:
Fe + 3Cl2 → FeCl2;
2) Iron (II) chloride reacts with sodium hydroxide, a precipitate of iron (II) hydroxide and sodium chloride is obtained:
FeCl2 + NaOH → Fe (OH) 2 ↓ + 2NaCl;
3) The precipitate of iron (II) hydroxide decomposes into ferum (II) oxide and water:
Fe (OH) 2 → FeO + H2O;
4) When ferum (II) oxide interacts with sulfuric acid, ferum (II) sulfate and water are formed:
FeO + H2SO4 → FeSO4 + H2O.
