Analytical Methods
By Bismuth or bismuth oxide dissolved in nitric acid, sulfuric acid increases in evaporation to 380 ° C sulfate derived smoke.
Specification
The Bismuth sulfate, with the CAS registry number 7787-68-0, is also known as Dibismuth trisulfate. Its EINECS number is 232-129-5. This chemical's molecular formula is Bi·3/2H2O4S and molecular weight is 356.12. What's more, its systematic name is bismuth(+3) trihydride cation trisulfate. It is used as analytics reagents and medicine, it is also used in pharmaceutical industry. It is used to determine other metal sulphate salts.
Preparation: 10 g bismuth metal which are gradually added into 20 mL nitric acid are completely dissolved. After that, add 15 mL sulfuric acid to the solution, then colorless precipitations are generated when heated and concentrated. The intermediate products are heated further at the temperature of 250-300 °C and then evaporate to dry untill the final weight no longer reduces. At this time, the crystallizations bismuth sulfate are prepared.
