SULFURIC ACID SOLUTION ELUENT CONCENTRA

General description

Sulfuric acid (hydrogen sulfate, sulphine acid,battery acid) is a clear, colorless, oily liquid and is very corrosive in nature towards both metal and tissues. It is soluble in water.

This eluent concentrate for ion chromatography is determined by potentiometric titration. Content and expiry date can be found on the certificate.

Application

Biochem/physiol Actions

It finds application in the manufacture of explosives, fertilizers, glue and other acids. It is also used in the pickling of metal, purification of petroleum, and in lead-acid batteries. It is widely used as dehydrating agent, catalyst, and as an active reactant in chemical industry. It is also suitable to control pH, ranging from saline solutions to strong fuming acids.

Sulfuric acid is prepared by dry distillation of minerals like copper sulfate pentahydrate (blue vitriol), and iron sulfate heptahydrate (green vitriol). On application of heat these compounds decompose to form iron and copper oxides thereby eliminating water and sulphur trioxide, which then combine to give, dilute solution of sulphuric acid.
