  • Inquiry

Bismuth sulfate, white needle crystal or powder. It’s acidic. In water or alcohol, it is broken down into basic salt. Heated to 465 ℃ is decomposed to emit sulphur trioxide. Soluble in dilute hydrochloric acid or dilute nitric acid, insoluble in water and alcohol. Bismuth oxide or hydroxide bi (III) with thick – H2SO4 for bi (III) sulfate, sulfuric acid and the metal bismuth, hot also can get bismuth sulfate (III), the crystal white solid Bi2 (SO4) 3 · nH2O (n = 2 or 7). It has to do with yttrium sulphate isomorphous, lanthanum, praseodymium. Bi (III) sulfate stability under 400 ℃, and above 400 ℃ is decomposed into basic salt and bismuth oxide (III), Bi (III) sulfate hydrolysis to produce under the influence of water insoluble basic salt (OH) 3 · Bi Bi (OH) 2 SO4, bismuth sulfate in sulfuric acid (III) there is no separate Bi (3 +), but a series of ligand ions.

Uses: Determination of other metal sulfate, analytical reagents, but also for the pharmaceutical industry.
Chemical Class: Inorganic Compounds
Storage & Handling: Store at Room Temperature (15-30 °C).
