Barium sulfate. Barium sulfate is a chemical compound composed of barium and sulfate ions. It contains barium in the +2 oxidation state, as in all barium compounds. It does not dissolve in water. If it did, it would be very toxic. It is used in X-rays of the stomach and intestines to see whether there is a problem with them.

Barium sulfate (barita) is the main commercial source of barium, although the metal will react with sulfuric acid to form the sulfate (), and it can be formed from an exchange reaction (e.g., 9). The latter works because of the sulfate’s low solubility in water ( K sp = 1.1 × 10 −10 ), which causes it to precipitate from solution.

Barium sulfate is used to identify the teeth from the diagnostic wax-up in a 20% BaSO4 solution. If a soft tissue (flapless surgery) template is to be made, teeth are ideally identified with a 20% BaSO 4 solution, and the base (soft tissue) uses a 10% mix. This allows for differentiation of the teeth from the soft tissue.
