Ferric Sulphate [Fe₂₍SO₄)₃] is a chemical compound having sulphate ions and iron in its oxidation state. Having a primary hazard as a threat to the environment, it is used as a soil conditioner. It is an iron molecular entity and has a role of a catalyst, mordant and astringent. It can form a soluble iron cation by reacting with organics, as its solution is corrosive.

CAS NO :- 10028-22-5

USES AND APPLICATIONS FOR FERRIC SULPHATE
