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 $Cu$.
