1) 4Fe + 3O2 = 2Fe2O3 – iron is oxidized to iron oxide.
2) Fe2O3 + 6HCl = 2FeCl3 + 3H2O – when chloride acid interacts with iron oxide, water and ferric chloride are released.
3) FeCl3 + 3NaOH = Fe (OH) 3 + 3NaCl – ferric chloride reacts with sodium hydroxide to form iron hydroxide and sodium chloride.
4) 2Fe (OH) 3 + 3H2SO4 = Fe2 (SO4) 3 + 6H2O – iron hydroxide reacts with sulfate acid to form iron sulfate and water.
5) Fe2 (SO4) 3 + 6НNO3 = 2Fe (NO3) 3 + 3Н2SO4 – ferrous sulfate reacts with nitrate acid to form ferrous nitrate and sulfate acid.
