Bismuth CAS 7440-69-9
Bismuth can self ignite in chlorine gas and directly combine with bromine, iodine, sulfur, and selenium to form trivalent compounds when heated. Insoluble in dilute hydrochloric acid and dilute sulfuric acid, soluble in nitric acid and concentrated sulfuric acid to form trivalent bismuth salts. The main minerals include bismuthinite and bismuthinite. The abundance in the Earth's crust is 2.0 × 10-5%.
