Question

Name the reaction in which one of the reacting species loses electrons while the other gains electrons.

Answer 1

Reduction and oxidation reactions

Answer 2

Explanation:

A reaction in which  one of the reacting species loses electrons while the other gains electrons is known as reduction-oxidation reaction.

For example, $H_{2} + F_{2} \rightarrow 2HF$

Oxidation: $H_{2} \rightarrow 2H^{+} + 2e^{-}$

Reduction : $F_{2} + 2e^{-} \rightarrow 2F^{-}$

Net reaction : $H_{2} + F_{2} \rightarrow 2H^{+} + 2F^{-} \rightarrow 2HF$
