Almost all of the barium consumed commercially is obtained from barite, which is often highly impure. General Reference Center GOLD. BaSO4 is insoluble in water because of water's dipole strength. 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. Although barium is a heavy metal, and its water-soluble compounds are often highly toxic, the low solubility of barium sulfate protects the patient from absorbing harmful amounts of the metal.

With a low surface area, the contact time of the substrate with the catalyst is shorter and thus selectivity is achieved. thanks. NH4Br = soluble because NH4 is soluble. Barite is processed by carbothermal reduction (heating with coke) to give barium sulfide: In contrast to barium sulfate, barium sulfide is soluble in water and readily converted to the oxide, carbonate, and halides. The anode plates are cast in copper molds, so to avoid the contact of the liquid copper and the solid copper mold, a solution of barium sulfate in water is used as a coating on the mold surface. NaCl is easily soluble in water; BaSO4 is insoluble. Thus when the liquid copper solidifies in form of an anode plate it can be easily released from its mold. The white opaque appearance and its high density are exploited in its main applications.[4]. asked Mar 9, 2018 in Class XI Chemistry by nikita74 (-1,017 points) Why are BeSO 4 and MgSO 4 readily soluble in water while CaSO 4, SrSO 4 and BaSO 4 … a.
