Sulphuric Acid
Sulphuric acid, H2SO4 is a strong mineral acid. It is soluble in water at all concentration. Sulphuric acid has many applications, and is one of the top products of the chemical industry. Principal uses include ore processing, fertilizer manufacturing, oil refining, wastewater processing, and chemical synthesis. Many proteins are made of sulphur-containing amino acids (such as cysteine and methionine) which produce sulphuric acid when metabolised by the body. Uses of sulphuric acid
