Oxidizing Agent:
Oxidizing agents are substances that;
1. supply oxygen,
2. remove hydrogen,
3. accept electrons,
4. are reduced in a chemical reaction.
Examples of oxidizing agents include electronegative elements like sulphur, oxygen, fluorine, chlorine, etc., concentrated tetraoxosulphate(VI) acid, potassium tetraoxomangnate (VII), potassium heptaoxodichromate(VI) etc.
Reducing Agent:
Reducing agents are substances that;
1. supply hydrogen,
2. remove oxygen,
3. lose electrons,
4. are oxidized in a chemical reaction.
Examples of reducing agents include Hydrogen, Carbon(IV) oxide, active metals generally, Sulphur(IV)oxide, Ammonium hydrosulphide, Potassium Iodide, etc.
Disproportionation Reaction:
A disproportionation reaction is a reaction in which a reactant acts as an oxidizing and a reducing agent.
