1. Chem. sulphuric acid, a highly corrosive oily fluid (hydrogen sulphate, H2SO4), also called oil of vitriol, in its pure state a dense liquid without colour or smell; prepared on a large scale for use in arts and trades by burning iron pyrites or sulphur and leading the fumes, together with oxides of nitrogen and air, over into chambers into which jets of steam are forced.
Formerly used also for sulphur trioxide, sulphuric acid gas, SO3; also called anhydrous sulphuric acid.
