Question

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

a. it’s neutralized
b. it’s oxidized
c. it has dissolved
d. it’s reduced
e. it has precipitated

Answer 1

d. it’s reduced

Step-by-step explanation:

An oxidation-reduction reaction, commonly known as REDOX reaction is a type of reaction that involves the transfer of electrons from one atom to another characterized by a change in oxidation number. The atom that loses electrons is said to be OXIDIZED while the atom that gains electrons is said to be REDUCED.

Therefore, in this question describing the half reaction of an oxidation reduction to show that iron atom (Fe) gains electrons. This indicates that the IRON atom is being REDUCED because it's oxidation number will reduce after gaining electrons.
