Solution

Definition of oxidation.
It is defined as a chemical process that involves the addition of oxygen or removal of hydrogen from an element or a compound in a reaction.
Addition of oxygen
$4 Fe + 3 O_{2} \to 2 {Fe}_{2} O_{3} iron oxygen iron oxide$
Removal of hydrogen
$H_{2} S + {Cl}_{2} \to 2 HCl + S Hydrogen - Chlorine Hydrogen - Sulphur sulphide sulphide$
Definition of reduction.
It is the reverse of oxidation. ie. removal of oxygen or the addition of hydrogen to an element or a compound.
Removal of oxygen.
$CuO + C \to Cu + CO Copper oxide carbon copper Carbon monoxide$
Addition of hydrogen.
$N_{2} + 3 H_{2} \to 2 {NH}_{3}$
Sl.No Oxidation Reduction
1 The process of adding oxygen or removing hydrogen from an element or a compound is called oxidation The process of removing oxygen or adding hydrogen to an element or compound is called reduction.
2 An oxidizing agent is a chemical species that tend to oxidize other substances. A reducing agent is oxidized because it loses electrons in the redox reaction.
3 Examples :oxygen,chlorine Examples : hydrogen, carbon
