Sulphuric acid is a strong corrosive mineral acid with molecular formula H2SO4. It is a colourless, odourless, and syrupy liquid that is soluble in water, in a reaction that is highly exothermic.

Its corrosiveness can be mainly ascribed to its strong acidic nature, and if at a high concentration its dehydrating and oxidizing properties. It is also hygroscopic, readily absorbing water vapour from the air. Upon contact, sulphuric acid can cause severe chemical burns and even secondary thermal burns; it is very dangerous even at moderate concentrations...
