![]() This procedure can also be applied for the indirect determination of CrO 4 2−, by measuring the AgCl obtained. ![]() The process can be repeated, and on each treatment with BaCl 2 an amount of silver chloride equivalent to twice the original silver chromate is produced after n cycles 2( n+1) moles AgCl can be found. These precipitates are treated with Ag + and thus 1 mol of Ag 2CrO 4 and 2 mol of AgCl are formed. Ag 2CrO 4 is filtered and then treated with barium chloride for the precipitation of both BaCrO 4 and AgCl. The direct amplification of silver can be carried out by precipitation with chromate. Wages Jr, in Encyclopedia of Analytical Science (Second Edition), 2005 Alternative Precipitation In the manufacture of caustic soda, polymers, and stabilizers. Īs a mordant in dyeing and printing textiles,.įor manufacturing of other barium salts used as pesticides, pigments, boiler detergent,.įor stimulating the heart and other muscles for medicinal purposes,.įor the production of PVC stabilizers, oil lubricants, barium chromate and barium fluoride,.įor making color kinescope glass ceramics,.Īs a flux in the manufacture of magnesium metal,.However, its toxicity limits its applicability, In fireworks to give a bright green color. In the manufacture of other barium salts such as barium hydroxide, In the manufacture of heat treatment salts, In the purification of brine solution in caustic chlorine plants, In industry, barium chloride is mainly used chiefly in the synthesis of pigments and in the manufacture of rodenticides and pharmaceuticals. It is commonly used as a test for sulfate ion. As a cheap, soluble salt of barium, barium chloride finds wide application in the laboratory. ![]() The dihydrate is stable in the air at room temperature, but loses one-half of its water above 55 ☌ (131 ☏), and becomes anhydrous at 121 ☌ (250 F). From water solutions of barium chloride, the dihydrate can then be crystallized as white crystals, BaCl 2♲H 2O, which are colorless, translucent rhomboidal tablets or lamellae. The BaCl 2 is then be leached out from the mixture with water.
