To make barium sulfate crystals, you would typically mix a solution of barium chloride with a solution of sodium sulfate. This would cause a precipitation reaction in which barium sulfate crystals form. These crystals can then be collected by filtration, washed, and dried to obtain the desired product.

Why is barium chloride and alcohol used in the limit test for sulphates?
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.
What is the balanced equation for barium sulfate is oxidized to barium sulfate by atmospheric oxygen?
Barium sulphate to barium sulphate is NO CHANGE!
How does barium occur naturally?
Can be used in Fluoirescent tubes and also make Paint, Bricks, Tiles, Glass and Rubber.
Why excess barium chloride is added to the filtrate in the preparation of a dry sample of barium sulphate?
Barium chloride in excess is added to be sure that the reaction is complete.
What happens when sodium sulphate react with barium chloride?
sodium carbonate and barium chloride react to form sodium chloride and barium carbonate Na2CO3 +BaCl2 -------> 2NaCl +BaCO3

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 are the factors that favor the formation of barium sulphate crystals?
Factors that favor the formation of barium sulfate crystals include the presence of high concentrations of barium and sulfate ions in the solution, low solubility of barium sulfate at the specific temperature, slow cooling rate, and agitation to promote crystal growth. Additionally, the presence of impurities or seed crystals can also facilitate the crystallization process.
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
How can you improve the yield of barium sulphate in a gravimetric analysis?
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.
What is barium sulphate?
A white, heavy, crystalline solid. A sulfate salt of Barium.
Is barium sulphate a compound or an element?
Barium sulfate (BaSO4) is a compound. It consists of three elements, barium, sulfur and oxygen chemically combined. Together these elements make up the compound.
