To improve the yield of barium sulphate in a gravimetric analysis, you can ensure complete precipitation by adding the appropriate amount of precipitating agent (sulfuric acid or barium chloride) slowly with stirring. Additionally, allowing the precipitate to settle and then filtering it using a fine filter paper can help to remove impurities and increase the yield. Washing the precipitate with the solvent used in the precipitation step can also improve the purity of the barium sulphate.

How do you determine the sulphate?
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.
Why hcl used in the limit test of sulphates?
Hydrochloric acid (HCl) is used in the limit test of sulphates because it helps in the precipitation of sulphates as insoluble barium sulphate (BaSO4). This makes it easier to quantitatively determine the amount of sulphate present in a sample through gravimetric analysis. The addition of excess HCl ensures that all sulphates are converted to BaSO4, allowing for accurate measurement.
Why do you add hydrochloric acid to test for sulphate?
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.
What is the symbol fol barium sulphate?
barium =Basulphate = SO4so barium solphate is BaSO4
How do you test for sulphate ions?
Sulphate ions can be tested by adding barium chloride solution to the sample. If sulphate ions are present, a white precipitate of barium sulphate will form. This precipitate confirms the presence of sulphate ions in the sample.

What compound containing potassium reacts with barium nitrate to form a white precipitate?
Potassium sulphate - K2SO4; the precipitate is BaSO4 - the reaction is frequently used in gravimetric analysis.

What is the balanced equation for barium sulfate is oxidized to barium sulfate by atmospheric oxygen?
Barium sulphate to barium sulphate is NO CHANGE!
What is the word equation for BaCl2 Na2SO4?
barium chloride plus sodium sulphate yields barium sulphate plus sodium chloride
What is observed when sodium sulphate solution is added to barium 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.
What is the reagent used in preparing barium sulphate?
sulf + barium
What is Ba2SO4?
Ba3As2 is barium arsenide. Ba2As3-- doesn'exist.
Formula of barium sulphate?
BaSO4
What is the chemical BaSO4?
Barium Sulphate
What is barium sulphate?
A white, heavy, crystalline solid. A sulfate salt of Barium.
