单词	chloride
释义	chloride /ˈklɔːrʌɪd / noun Chemistry A compound of chlorine with another element or group, especially a salt of the anion Cl− or an organic compound with chlorine bonded to an alkyl group: the presence of sulphates, chlorides, and nitrates [with modifier]: sodium chloride... Leachate typically contains organic compounds together with metal chlorides and sulphates, and has a high chemical oxygen demand due to the presence of reducing species. The carboxyl group is fairly reactive, and carboxyl group-containing compounds can undergo nucleophilic substitution to form many useful derivatives such as acid chlorides, anhydrides, esters, and amides. Inorganic anions such as chloride, nitrate and sulphate can be separated in about five minutes. Origin Early 19th century: from chlorine + -ide.
