Question

Fe+S=Fes is oxidation or reduction

Answer 1

Bro... It is a redox reaction....

Because reduction and oxidation reactions are taking place simultaneously....

Answer 2

Answer : This reaction is a redox reaction or oxidation-reduction reaction.

Explanation :

• Oxidation-reduction reaction : It is a reaction in which oxidation and reduction reaction occur simultaneously.
• Oxidation reaction : It is the reaction in which a substance looses its electrons. In this oxidation state increases.
• Reduction reaction : It is the reaction in which a substance gains electrons. In this oxidation state decreases.

The given balanced chemical reaction is,

$Fe+S\rightarrow FeS$

Half reactions of oxidation and reduction are :

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

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

In this reaction, iron is oxidized from (0) to (+2) oxidation state and sulfur is reduced from (0) to (-2) oxidation state.

Hence, this reaction is a redox reaction or oxidation-reduction reaction.
