Explain the "Reduction'' in terms of gain or loss of oxygen with two examples.

Option A

Option B

Option C

Option D

Solution

Reduction is the loss of oxygen.

For example :

$(i)$ $\mathop {C{O_2}\, + \,{H_2}\, \to \,CO}\limits_{{\text{Removal of oxygen – reduction}}} \, + \,{H_2}O$

$(ii)$ $\mathop {CuO\, + {H_2}\,\xrightarrow{\Delta }\,Cu}\limits_{{\text{Loss of oxgyen – reduction}}} \, + \,{H_2}O$

In equation $(i)$, $CO_2$ is reduced to $CO$ and in equation $(ii)$, $CuO$ is reduced to $Cu$.
