Redox Titration

Redox titration is based on transfer of electron from reducing agents to oxidizing agents.
Oxidation – loss of electron
Reduction – gain of electron

Oxidizing agents gains electrons and reduce to lower oxidation state whereas reducing agent losses electrons and oxidize to higher oxidation state. Oxidation and reduction occurs simultaneously and so called as redox titration or oxidation-reduction titration.

Oxidizing agents: Potassium permanganate
Potassium iodide
Ceric ammonium sulphate

Reducing agents: Oxalic acid
Sodium thiosulphate
Ferrous ammonium sulphate
Titanium sulphate

Indicator used in redox titration are shown in table

Indicator	Color change
	Oxidized form	Reduced form
Starch	Blue	Colorless
Diphenylamine	Violet	Colorless
Diphenylbenzidine	Violet	Colorless
Methylene blue	Blue	Colorless
Diphenylaminesulphonic acid	Red-violet	colorless

Application of Redox titration:
For determination of metals like Ca, Mg, Co, Ni, Iron etc
For determination of dissolved oxygen, hydrogen peroxide and anions such as NO2^-, Cl, Br^-, SO3^2-
To determine oxidized state of elements
