sulphuric

Sulphuric acid, also known as hydrogen sulfate, is a mineral acid with the chemical formula H2SO4. It is a colourless, oily liquid that is soluble in water and is synthesized in the contact process. Sulphuric acid is a strong acid and is highly corrosive, capable of causing severe burns and chemical damage. It is a diprotic acid, meaning it can donate two protons in a reaction. Sulphuric acid is widely used in various industries, including fertilizers, detergents, and petroleum refining. It is also used in the production of other chemicals, such as nitric acid and hydrochloric acid. In the laboratory, sulphuric acid is used as a dehydrating agent and in various chemical reactions. However, due to its corrosive nature, it must be handled with extreme care. Sulphuric acid is also a significant air pollutant, contributing to acid rain. The global annual production of sulphuric acid is estimated to be around 200 million tonnes.
