Detailed Solution

The above statement is true.
From the perspective of the molecule being reduced, a reduction reaction is one in which one molecule is reduced, and another is oxidised. A redox reaction is a name given to the entire process. This is a helpful approach to keeping things in mind.
When discussing electrons, the phrase "OIL RIG" might be used to help recall this.
OIL = Oxidation Is Loss of electrons, and RIG= Reduction Is Gain of electrons
A substance undergoes oxidation when it:
1)     Loses one or more electrons
2)     gains a proton or an electron, or both.
3)     loses an electron or an atom of hydrogen
4)     increases in terms of oxidation number
In the reduction process, a substance:
1)     increases by one or more electrons
2)     Electronegative atoms or the loss of an oxygen atom
3)     gains an electropositive atom or a hydrogen atom
4)     decreases in oxidation number
