Silver thioarsenates

Silver Thioarsenates.—Silver Ortkothioarsenate, Ag3AsS4, is formed as a dark brown precipitate when an aqueous solution of silver nitrate is treated with sodium orthothioarsenate.1 If, however, silver nitrate is added to a solution of sodium orthothioarsenate, silver orthothioarsenate is not formed but silver sulphide is precipitated and arsenious acid, nitric acid and sodium nitrate are formed in solution.8 The reactions involved probably take the following course 3... [Pg.279]

The alkali salts are generally formed when arsenic pentasulphide is dissolved in an aqueous solution of the hydrosulphide and the mixture evaporated or precipitated with alcohol, or when a solution of an arsenate is treated with hydrogen sulphide under suitable conditions. The thioarsenates of the heavy metals (except silver, see p. 279) may be formed by the action of an excess of an alkali thioarsenate on a salt of the heavy metal if the latter is in excess the sulphide is formed.4... [Pg.274]
