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.

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.

Barium carbonate is soluble in plain water

the major pests we deal with are insects, weeds and fungal diseases. a pesticide is a product, whether organic or chemical, used to kill the target pest. there are other techniques gardeners should use that can prevent the severe infestations that make the use of pesticides necessary

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
