A) USES: Barium sulfate is used as an oral or rectal contrast agent in radiologic studies. In industry it is used as a lubricant, as a pigment in paints, and in manufacturing of cellophane, photographic papers, brake linings and adhesives. B) PHARMACOLOGY: Barium is used in radiologic procedures because it is radiopaque.

22/09/2021 · Since barium chloride is added in excess, and since the precipitation reaction goes to completion, we can assume that all of the sulfate is transferred from the original unknown sample to the precipitate. The mass of sulfate in the collected (ce{BaSO4}) precipitate can be calculated via its percent composition.

Gravimetric Sulfate Determination. A sample containing an alkali sulfate is dried, weighed and dissolved in dilute HCl. Barium chloride solution is added in excess to precipitate barium sulfate, and the precipitate is digested in the hot solution. The precipitate is filtered through a paper filter which is then ignited and completely ashed.

SOLUBLE ANHYDRITE, which is obtained by heating calcium sulfate dihydrate at a temperature below 300°C, has a high affinity for water and is used as a desiccant. Soluble anhydrite absorbs water to form calcium sulfate hemihydrate (Plaster of Paris).

Copper sulfate is an inorganic compound that combines sulfur with copper. It can kill bacteria, algae, roots, plants, snails, and fungi. The toxicity of copper sulfate depends on the copper content. Copper is an essential mineral. It can be found in the environment, foods, and water. Copper sulfate has been registered for use in pesticide ...

Sulfate Ions: Sulfate is conveniently identified by precipitation of BaSO 4. Other insoluble barium salts contain anions of weak acids (CO 3 2, SO 3 2and PO 4 3). Precipitation of these anions is prevented by acidifying the solution. Acidify the test solution with 6 .
