Solution

The addition of oxygen to a substance is called oxidation whereas removal of oxygen is called reduction.

Explanation:

Oxidation occurs when a substance gains oxygen or loses electrons during a chemical reaction. Reduction is the exact opposite process, where a substance loses oxygen or gains electrons. These two processes always happen together in what is known as a redox reaction.
