In oxidation state +3, bismuth forms trihalides with all of the halogens: BiF 3, BiCl 3, BiBr 3, and BiI 3. All of these except BiF 3 are hydrolyzed by water. Bismuth(III) chloride reacts with hydrogen chloride in ether solution to produce the acid HBiCl 4. The oxidation state +5 is less frequently encountered. One such … See more Bismuth is a chemical element with the symbol Bi and atomic number 83.
