Bismuth Reduction

Chemical Formula: Bi
Present as: elemental metal

Bismuth is a chemical element with the symbol Bi and the atomic number 83. Bismuth is a heavy metal that has similar properties to antimony and arsenic. Elemental bismuth may occur naturally, although its sulfide and oxide form important commercial ores. The free element is 86% as dense as lead. It is a brittle metal with a silvery white color when freshly produced but is often seen in air with a pink tinge owing to surface oxidation. Bismuth is the most naturally diamagnetic element, and has one of the lowest values of thermal conductivity among metals.
Bismuth metal has been known since ancient times, although it was often confused with lead and tin, which share some physical properties. The etymology is uncertain, but possibly comes from Arabic bi ismid, meaning having the properties of antimony or the German words weiße Masse or Wismuth (“white mass”), translated in the mid-sixteenth century to New Latin bisemutum.
It has low toxicity and is used in cosmetics, and in diarrhea medications. It is a semiconductor, which, when alloyed with antimony or selenium, is an efficient thermoelectric material for refrigeration or portable power generation. Bismuth is relatively insoluble in water but forms a trivalent cation in acidic solutions and a complex anion in very concentrated acids.
