Bismuth arsenite

Bismuth Arsenite.—When arsenious acid acts upon a solution of sodium bismuth chloride, a white precipitate of approximate composition BiAsO3.5H20 is formed.6 The substance has not been obtained pure. It is not decomposed by boiling aqueous alkali 7 it is soluble in nitric acid.8...

Bismuth subuitrate. aa well the subcarl>onate. is liable to contamination with arsenic, which accompanies bismuth in its ores. The method for sepamtiug this British Pharmacopoeia. is more perfect than that usually followed in this country. The metal is first purified by fusion with potassium nitrate, which dissolves anv arsenic present in the form of soolium arsenite, and the purified metal... 

An excess of boiling trifluoroacetic anhydride reacts with sodium arsenite to give the compound NaAs0(CF3C02)2 in good yield, and similar bismuth reactions also take place. Polarographic and potentiometric measurements in aqueous solution point to the formation of a complex [As(OH)2HX]" between arsenic(iii) and nitrilotriacetic acid (HaX). ...

Preparative aspects. Since bonds between carbon and arsenic, antimony and bismuth are stable to water they may be made in aqueous solution. Thus, alkyl arsonic adds RAs(OH)2 may be prepared by the Meyer reaction between sodium arsenite and alkyl halides ...
