Question

Although soluble barium compounds are toxic, suspensions of insoluble barium sulfate are routinely swallowed for upper gastrointestinal x-ray studies. why is barium carbonate not used? 1. barium carbonate is soluble in plain water. 2. stomachs contain hcl and all carbonates dissolve in acid. 3. all carbonates are toxic, whether soluble or not. 4. barium carbonate is too expensive.

Answer 1

From a chemistry book that I have read, it stated that Barium Sulfate is so insoluble in water. Due to this, it is not toxic to humans since it is not dissolved and absorbed by our body. In the other hand, Barium Carbonate is slightly soluble in water making it toxic to us.

 

Answer:

Barium carbonate is soluble in plain water
