Bismuthiol II as an analytical reagent
Bismuth and palladium were determined volumetrically after precipitation as bismuthiol II complexes. Bismuth-bismuthiol complex was dissolved in excess of EDTA (disodium salt) at a pH of about 10 and the excess of the EDTA was back titrated with magnesium solution. Palladium complex on the other hand was dissolved in cyanide, the excess of which was back titrated with silver nitrate. The results of bismuth were highly satisfactory but those due to palladium were accurate within about-1%.
