On the analogy of hydrogen chloride, etc., acids are often named as salts of hydrogen, e.g. hydrogen acetateC2H3O2.H, hydrogen chlorate HClO3, hydrogen chlorite HClO2, hydrogen nitrate HNO3, hydrogen sulphate H2SO4, hydrogen sulphite H2SO3 (= acetic, chloric, chlorous, nitric, sulphuric, sulphurous acids).
