Bismuth v oxide
WebThe dark red bismuth(V) oxide, Bi 2 O 5, is unstable, liberating O 2 gas upon heating. The compound NaBiO 3 is a strong oxidising agent. Bismuth sulfide, Bi 2 S 3, occurs naturally in bismuth ores. It is also produced by the combination of molten bismuth and sulfur. WebBismuth oxide is used as a yellow pigment for cosmetics and paints, while bismuth (III) chloride oxide (BiClO) gives a pearly effect to cosmetics. Basic bismuth carbonate is taken in tablet or liquid form for indigestion as ‘bismuth mixture’.
