Question

3Fe+4H2O------>Fe3O4+4H2, identify the type of reaction

Answer 1

it is redox reaction as Fe is oxidized and H is reduced

Answer 2

Fe is a reducing agent and is an oxidizing agent

Explanation:

Oxidation reaction : When there is an increase in oxidation state number.

Reduction reaction : when there is a decrease in oxidation state number.

Iron metal has undergone oxidation, as its oxidation state is changing from 0 to +2 and +3. Iron metal is getting converted into Iron ions.

Hydrogen has undergone reduction, as its oxidation state is changing from 2+ to 0.Hydrogen ions are getting converted into hydrogen.

is a reducing agent

Those chemical agents which get oxidized itself and reduce others is called reducing agents.

is an oxidizing agent

Those chemical agents which itself get reduced and oxidize others is called oxidizing agents.
