Definition of Oxidation
If you are a fan of oxygen-based cleaners, or grateful for the sterilizing powers of hydrogen peroxide, then you have oxidation to thank. On the other hand, if you've ever had to deal with a rusty car or toss out browned fruit, then you have oxidation to blame. Oxidation may be a spontaneous process or it may be started artificially. Sometimes it is helpful, and sometimes it is very destructive.
At its most basic level, oxidation is the loss of electrons. It happens when an atom or compound loses one or more electrons. Some elements lose electrons more easily than others. These elements are said to be easily oxidized. Generally speaking, metals including sodium, magnesium, and iron are easily oxidized.
Elements that are more reluctant to lose electrons are not easily oxidized; they hold onto their electrons very tightly. Nonmetals including nitrogen, oxygen, and chlorine are not easily oxidized.
Answer:
If a substance gains oxygen during a reaction it is said to be oxidised. This process is called oxidation reaction.
eg CuO + H2 gives Cu+ H2O
Explanation:
In this reaction copper oxide is getting reduced to copper and hydrogen is getting oxidised .
