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