Question

Write short notes on:
Reduction reaction

Hint:

Reduction is the gain of electrons or a decrease in oxidation state. It occurs simultaneously with oxidation in redox reactions.

Answer 1

A reduction reaction involves the gain of electrons or a decrease in oxidation state. It often occurs alongside oxidation in redox reactions. Example: \[ \text{CuO} + \text{H}_2 \rightarrow \text{Cu} + \text{H}_2O \] Here, \( CuO \) is reduced to \( Cu \) by gaining electrons.
