Bismuth hydroxide ({{chem|Bi|(|O|H|)|3}}) is a non-fully characterised chemical compound of bismuth. It is produced as white flakes when alkali is added to a solution of a bismuth salt and is usually described as bismuth oxide hydrate{{Holleman&Wiberg|page=771}} or bismuth hydrate.{{Cite web|url=http://www.chemicalbook.com/ChemicalProductProperty_EN_CB1745168.htm|title = Bismuth Hydroxide | 10361-43-0}} Upon heating to 400°C, bismuth hydroxide decomposes to bismuth(III) oxide.{{Cite journal |last=Patil |first=M.
