Q: What is Barium Sulphate? A: Barium Sulphate is the inorganic compound with the chemical formula BaSO4. It is a white crystalline solid that is insoluble in water. It occurs as the mineral barite, which is the main commercial source of barium and materials prepared from it. More detail click here! Q: How the production of Barium Sulphate? A: Almost all of the barium consumed commercially is obtained from the mineral barite, which is often highly impure. Barite is processed by carbothermal reduction (heating with coke) to givebarium sulfide: BaSO4 + 4 C → BaS + 4 CO Barium sulfate produced in this way is often called blanc fixe, which is French for "permanent white." Blanc fixe is the form of barium encountered in consumer products, such as paints. In the laboratory barium sulfate is generated by combining solutions of barium ions and sulfate salts. Because barium sulfate is the least toxic salt of barium due to its insolubility, wastes containing barium salts are sometimes treated with sodium sulfate to immobilize (detoxify) the barium. Barium sulfate is one of the most insoluble salts of sulfate. Its low solubility is exploited in qualitative inorganic analysis as a test for Ba2+ ions as well as for sulfate. Q: How the history of Barium Sulphate? A: Barium sulfate is reduced to barium sulfide by carbon. The accidental discovery of this conversion many centuries ago led to the discovery of the first synthetic phosphor (Hollman and Wiberg, 2001). The sulfide, unlike the sulfate, is water soluble. Sometime prior to the autumn of 1803, the Englishman John Dalton was able to explain the results of some of his studies by assuming that matter is composed of atoms and that all samples of any given compound consist of the same combination of these atoms. Dalton also noted that in series of compounds, the ratios of the masses of the second element that combine with a given weight of the first element can be reduced to small whole numbers (the law of multiple proportions). This was further evidence for atoms. Dalton's theory of atoms was published by Thomas Thomson in the 3rd edition of his System of Chemistry in 1807 and in a paper about strontium oxalates published in the Philosophical Transactions. Dalton published these ideas himself in the following year in the New System of Chemical Philosophy. The symbol used by Dalton for barium is shown below. Q: What is Barium Sulphate used for? A: Barium Sulphate was used extensively as a fertilizer and a raw material for the manufacture of gunpowder in the late 19th century. It can be combined with iron hydroxide to make a resin. Barium Sulphate should not be confused with the related compound, sodium nitrite. Barium Sulphate in the brine gives cooked corned beef its classic reddish color (without it corned beef comes out gray), and it kills botulism spores. Nitrate is actually changed to nitrite by bacterial action during processing and storage and nitrate itself has no effect on meat color. It can be used in the production of nitric acid by combining it with sulfuric acid and subsequent separation through fractional distillation of the nitric acid, leaving behind a residue of sodium bisulfate. Hobbyist gold refiners use Barium Sulphate to make a hybrid aqua regia that dissolves gold and other metals. Less common applications include its use as a substitute oxidizer used in fireworks as a replacement for potassium nitrate commonly found in black powder and as a component in instant cold packs. Barium Sulphate is used together with potassium nitrate for heat storage and, more recently, for heat transfer in solar power plants. It is also used in the wastewater industry for facultative microorganism respiration. Nitrosomonas, a genus of microorganisms, consumes nitrate in preference to oxygen, enabling it to grow more rapidly in the wastewater to be treated.
