Barium Sulfate - BaSO4

What is Barium Sulfate (BaSO4)?

BaSO4 is an inorganic compound with the chemical name Barium Sulfate.

Barium Sulfate is composed of a barium cation and the sulfate anion. The sulfur is attached to four oxygen atoms. BaSO4 is a sulfate salt of barium and is found as mineral barite. It is a crystalline solid white in color which is insoluble in water and alcohol but soluble in concentrated acids. It is odorless.

Barium Sulfate is an alkaline, divalent metal. It is non-toxic and is safe for medical use. It is widely used in the production of oil and natural gas to get high-density drilling fluids by keeping the boreholes free of rock.

Frequently Asked Questions

What are the side effects of barium sulfate?

Common side effects can include minor cramps in the stomach; nausea, vomiting; or. Stools loose, or moderate constipation. Extreme cramping, diarrhea or constipation; ringing in the ears; sweating, anxiety, rapid heart rate; or light skin, gray eyes, fatigue.

Is barium sulfide soluble in water?

For uses such as water treatment, most metal sulfate compounds are readily soluble in water, unlike the fluorides and oxides that appear to be insoluble.

Is barium sulfate soluble in hexane?

Sodium sulfate is a white powder that is highly soluble in water but not soluble in hexane (a hydrocarbon liquid). Dissolved wat, if added to the barium nitrate. Sodium sulfate is a white powder that is highly soluble in water but not soluble in hexane (a hydrocarbon liquid).

How do you make barium sulfate?

The barium sulfate is prepared by sodium sulfate reacting to barium chloride. The precipitate forms the barium sulfate.

Is barium sulfate an acid or base?

BaSO4 is known as barium sulfate. This is a salt. A salt can be formed from the acids and bases reaction. If we monitor the BaSO4 development reaction, we can see that Ba^2 + comes from the base, and that SO4^2- comes from the acid.
