Description

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 certified eluent concentrate for ion chromatography is traceable by potentiometric titration to NIST Standard Reference Material. It is certified in accordance with ISO Guide 31. All details about exact content, uncertainty, traceability and expiry date are described in the certificate.

Application

Metrohm IC application noteAN-S-344:Anions in "Electronic grade" nitric acid on a high-capacity column.

Metrohm IC application noteAN-S-341:4-Hydroxybutyrate in addition to standard anions and organic acids.

Metrohm IC application noteAN-S-336:Anion traces on the Metrosep A Supp 16 - 250/2.0 after Inline Preconcentration and Matrix Elimination

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.
