In a third process, barium sulfide (BaS) reacts with nitric acid to make barium nitrate and hydrogen sulfide:
Barium sulfate is commonly used in these types of scenarios. Barium sulfate has a lot of the exact same Houses as bony materials. As a result, due to the fact X rays will not likely go through barium sulfate, this compound may be used to examine certain smooth tissues.
