1. Iron oxide dissolves in hydrochloric acid to form chloride.
Fe2O3 + 6HCl = 2FeCl3 + 3H2O.
2. Reaction with nitric acid to form nitrate.
FeCl3 + 3HNO3 = Fe (NO3) 3 + 3HCl.
3. Reaction with alkali.
Fe (NO3) 3 + 3NaOH = 3NaNO3 + Fe (OH) 3.
4. Decomposition of iron hydroxide at 500-700 ° C.
2Fe (OH) 3 = Fe2O3 + 3H2O.
