There is no such word as "precificated" so the question cannot be understood.
Barium sulphate to barium sulphate is NO CHANGE!
Barium chloride is used in the limit test for sulphates because it forms a precipitate with sulphate ions. Alcohol is added to the mixture to promote the formation of small crystals, which makes it easier to detect the presence of sulphate ions in the sample.
Barium chloride in excess is added to be sure that the reaction is complete.
sodium carbonate and barium chloride react to form sodium chloride and barium carbonate Na2CO3 +BaCl2 -------> 2NaCl +BaCO3
No. Any sulphate is SO4.
Barium sulphate to barium sulphate is NO CHANGE!
barium chloride plus sodium sulphate yields barium sulphate plus sodium chloride
A white precipitate of barium sulphate is formed when sodium sulphate solution is added to barium chloride solution. This is due to the formation of an insoluble salt, barium sulphate, which appears as a white solid in the solution.
sulf + barium
Ba3As2 is barium arsenide. Ba2As3-- doesn'exist.
BaSO4
Barium Sulphate
A white, heavy, crystalline solid. A sulfate salt of Barium.
Hydrochloric acid is added to a solution being tested for sulphate ions to precipitate the sulphate as barium sulphate. This is a confirmatory test for the presence of sulphate ions in the solution because barium sulphate is insoluble and forms a white precipitate.
Sulphate ions can be determined using methods such as gravimetric analysis, titration with barium chloride, or ion chromatography. In gravimetric analysis, sulphate ions are precipitated as barium sulphate and weighed. Titration with barium chloride involves adding a known volume of barium chloride solution to the sample containing sulphate ions, and the excess barium chloride is back-titrated with a standard solution of a titrant such as potassium chromate. In ion chromatography, separation and quantification of sulphate ions are done using a chromatographic column with specific properties.
the ans is BaSO4
no.
