Abstract
1311001 Selenourea complexes ILFORD Ltd 6 Jan 1971 [13 Jan 1970] 1617/70 Heading C2C [Also in Division G2] A selenourea-silver thiosulphate complex is prepared by dissolving selenourea in a solution (A) of boric acid, borax and sodium thiosulphate pentahydrate in water and adding the resulting solution to a suspension of silver nitrate and sodium hydrogen carbonate in water dissolved in solution (A) to obtain the complex as a white precipitate. A complex with AgCl is also prepared.
