Oxidation and Reduction Reaction
Oxidation
Addition of oxygen to a substance or removal of hydrogen from a substance.
Reduction
Addition of hydrogen or removal of oxygen from a substance.
Redox Reaction
Those reactions in which oxidation and reduction occurs simultaneously are called Redox Reaction.
Oxidising Agent
The substance which give oxygen or substance which removes hydrogen.
Reducing Agent
The substance which give hydrogen or removes oxygen.
For Example:
1) CuO+H2(g)→ Cu+ H2O (l)
CuO is reduced to Cu
H2 is oxidised to H2O
CuO is the oxidising agent
H2 is the reducing agent
2) H2S + Cl2 → S + 2HCl
H2S is oxidised to S
The substance which gets oxidised is Reducing Agent.
The substance which gets reduced is Oxidising Agent.
