Bismuth bi
WebBismuth(III) nitrate pentahydrate is the hydrated form of bismuth(III) nitrate. It is effectively used as a Lewis acid catalyst in organic synthesis for the conversion of thiocarbonyls to their carbonyl compounds; aromatic nitration; protection of carbonyl compounds; Michael reactions, and synthesis of coumarins. Application WebBismuth is a white, crystalline, brittle metal with a pinkish tinge. Bismuth is the most diamagnetic of all metals, and the thermal conductivity is lower than any metal except mercury.
