High Quality Content by WIKIPEDIA articles! In chemistry the term zincate refers to an alkali solution prepared from dissolving zinc metal, zinc hydroxide or zinc oxide which contains various anionic species such as Zn(OH)42 . SUch solutions are used in the plating industry. IN the naming of inorganic compounds zincate is a suffix that indicates that a polyatomic anion contains a central zinc atom. EXamples include the following anions, tetrachlorozincate , ZnCl42 , the tetrahydroxozincate , Zn(OH)42 and tetranitratozincate, Zn(NO3)42 . MOre recent recommendations (2005), that are not widely used, would call the first two ions tetrachloridozincate(2 ) and tetrahydroxidozincate(2 ) respectively.
