The hall reaction of an oxidation-reduction reaction shows that iron gains electrons. What does this electron gain mean for iron? A
It is neutralized
B.
It is oxidized
C. It is reduced
D.
It has dissolved.
E
It has precipitated

Iron gains electrons mean It is reduced

Explanation:

Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.

Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

Thus iron gains electrons mean It is reduced
