WebBismuth(III) oxide powder Bismuth compoundsare compounds containing the element bismuth(Bi). Bismuth forms trivalent and pentavalent compounds, the trivalent ones being more common. Many of its chemical properties are similar to those of arsenicand antimony, although they are less toxic than derivatives of those lighter elements. [1] WebThe formula of bismuth (III) chloride is BiCl3. The Molecular mass of bismuth (III) chloride is 315.34 g/mol. The Boiling point of bismuth (III) chloride is 447℃ and therefore the freezing point is 230 to 232℃. Its appearance is pale yellow solid. Processes like alcoholysis, acetolysis, and hydrolysis, BiCl3 is used as a catalyst.
