Question

 Give  two  examples  of  oxidation  –  Reduction  reaction?

Answer 1

CuO+H2⇒Cu+H2O
This is reduction reaction

CaH2+O2⇒CaO+H2
This oxidation reaction

Answer 2

Two examples of oxidation-reduction reaction

Explanation:

• The type of chemical reaction in which among the two reactants involved in the reaction, one is oxidized and one is reduced simultaneously it is called a oxidation-reduction reaction.
• The reactant which loses oxygen is considered as reduced whereas the reactant which gains oxygen is considered as oxidized.

Examples of Oxidation-reduction reaction

• The chemical reaction in which such process occurs are as follows:

1. $CuO+H_2\rightarrow Cu+H_2O$

• It is a oxidation reduction reaction because, CuO is reduced to Cu, whereas $H_2$ is oxidized to $H_2O$.

2. $ZnO+C\rightarrow Zn+CO$

• In this case, ZnO is reduced to Zn, whereas C is oxidized to CO.
