Question

fe >s =fes what is reaction oxidation or reduction

Answer 1

S0 + 2 e- → S-II (reduction)

Fe0 - 2 e- → FeII (oxidation)

Change the oxidation states

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 => FeS

Half reactions of oxidation and reduction are :

Oxidation : Fe => Fe^2++2e-

Reduction : S + 2e- => S^2-

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

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