Which of the following oxide(s) of iron would be obtained on prolonged reaction of iron with steam?
Iron (Fe) reacts with steam (H2O) for a prolonged period of time to give Ferroso-ferric oxide (Fe3O4) and hydrogen gas (H2) as follows:
A redox reaction is a reaction in which both oxidation and reduction take place. Oxidation involves addition of oxygen and reduction involves removal of oxygen. In the given reaction, Iron is being oxidized to its oxide and Water is being reduced to hydrogen gas.
