| 释义 | > as lemmashydrogen chlorate (a) In systematic names of chemical compounds of hydrogen with an element or radical = ‘of hydrogen’: as hydrogen bromide HBr, hydrogen chloride HCl, hydrogen iodide HI (also called hydrobromic, hydrochloric, and hydriodic acids); hydrogen monoxide or hydrogen protoxide H2O (water), hydrogen dioxide H2O2 (oxygenated water); hydrogen arsenide H3As, hydrogen selenide H2Se, hydrogen sulphide H2S (also arseniuretted, seleniuretted, sulphuretted hydrogen); hydrogen disulphide H2S2, hydrogen potassium carbonate HKCO3, hydrogen sodium arsenate HNa.AsO4 + 12H2O. 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).
