Sulphuric acid : Description and use

Description

Formerly known as oil of vitriol or fuming sulphuric acid, sulphuric acid is a mineral acid. Its strength (pKa = -3.0) is exceeded by only a few superacids.
Concentrated sulphuric acid is not to be confused with fuming sulphuric acid, also known as oleum. The latter is a solution of 10 to 80% sulphur trioxide in anhydrous sulphuric acid.
Sulphuric acid is also available in the form of aqueous solutions in various concentrations. The acid used in lead-acid batteries has a content of under 51%.

Flammability: Sulphuric acid is a non-flammable liquid, which takes the form of a hygroscopic, oily, colourless and odourless liquid. However, if sulphuric acid comes into contact with combustible materials it can produce enough heat to cause a fire. Sulphuric acid reacts with most metals, especially if water is present, releasing hydrogen, a flammable and explosive gas.

USE

Base product in the manufacture of several chemical products (alcohols, mineral sulphates, detergents, etc.)
To manufacture explosives
Oil industry, textile industry, pulp and paper industry, pharmaceutical industry
Processing metals (leaching, pickling, electrolytic treatment)
Batteries
Dehydrating agent
Laboratory use
etc.
