Summary
Bismuthiol II reacts with trivalent arsenic and antimony to form complexes of compositions As(C8H5N2S3)3 and Sb(C8H5N2S3)3 respectively, while with stannous the reaction is not stoichiometric. The ions of arsenic and antimony can be estimated, from an acid solution, 0.1 N in hydrochloric or sulphuric acid, with the ammonium or the sodium chloride as the coagulant. The complexes have low melting points and they are soluble in organic solvents.
