Product Details Barium chloride is an inorganic salt with the chemical formula BaCl2. The compound is readily soluble in water and is toxic. This salt is often used for a quick test for the presence of sulfate ions; for example, sodium sulfate (Na2SO4). The test is a common laboratory assignment in chemistry, and is based on the formation of barium sulfate, which is insoluble in water.
Usage This salt is often used for a quick test for the presence of sulfate ions
-Pour the sample you need to test into a small beaker or a test tube.
-Use Glass Rod and Crush to fine powder
-Add five drops of the BaCl2 solution from the the test sample.Heat the test tube and Place under Microscope
-Observe the test solution; the formation of white precipitate indicates the presence of sulfate ions. The sulphides will start the show this the presence of little crystals or in a white snow like powder.Note that reaction follows the equation: BaCl2 + Na2SO4 = BaSO4 + 2NaCl.
