Obtain experimentally from ferric chloride 3 ferric oxide 3.

Solution to the problem: in this case, it is possible to obtain iron (III) oxide from iron (III) chloride using at least two equations of chemical reactions, namely:
1. Interaction of iron (III) chloride with sodium hydroxide with the formation of a water-insoluble base of iron (III) hydroxide and sodium chloride:
FeCl3 + 3NaOH = Fe (OH) 3 (precipitate) + 3NaCl;
2. Thermal decomposition of iron (III) hydroxide with the formation of iron (III) oxide and water (heating to about 350 – 400 degrees):
2Fe (OH) 3 = Fe2O3 + 3H2O.
