The half reaction of an oxidation-reduction reaction shows that iron gains electrons. What does this electron gain mean for iron?

ОА.

It is neutralized.

OB.

It is oxidized.

ОС.

It is reduced.

OD.

It has dissolved.

ОЕ.

It has precipitated.

Answer:The answer is C

Explanation:

Redox reaction is made up of two halves. That is a reduction half and a oxidization half. In the reduction half electrons are gained which result to decrease in oxidation number.

In the Oxidization half electrons are lost which result to increase in oxidation number.

iron is therefore reduced since it gains electrons
