Why does the white colour disappear when aqueous HCl is added to barium sulphate?
The white color of barium sulfate (BaSO₄) disappears upon the addition of aqueous hydrochloric acid (HCl) because HCl reacts with barium sulfate to form soluble barium chloride (BaCl₂) and sulfuric acid (H₂SO₄). The dissolution of BaSO₄, which is a white precipitate, results in the loss of its characteristic color. The reaction effectively removes the solid phase of barium sulfate from the mixture, leading to a clear solution.
Why was ionic precipitation chosen for the reaction of zinc sulphate and barium chloride?
Ionic precipitation was chosen for the reaction of zinc sulfate and barium chloride because it involves the formation of insoluble solid precipitates (zinc chloride and barium sulfate) from the combination of aqueous solutions of the two salts. This allows for the easy separation of the formed solid from the remaining solution.
How many liters of water are required to dissolve 1 of barium sulfate?
Barium sulfate (BaSO₄) is known for its very low solubility in water, with a solubility product (Ksp) indicating that only about 0.0002 grams can dissolve in 1 liter of water at room temperature. Therefore, to dissolve 1 gram of barium sulfate, an impractically large volume of water—approximately 5,000 liters—would be needed. This highlights the compound's nature as a sparingly soluble salt.
What are the reagents of barium sulfate?
The reagents needed to form barium sulfate are barium chloride and sodium sulfate. When these two compounds are mixed in solution, a white precipitate of barium sulfate forms.
What is the balanced equation for barium sulfate is oxidized to barium sulfate by atmospheric oxygen?
Barium sulphate to barium sulphate is NO CHANGE!
Does barium sulfate dissolve in hydrochloric acid?
Barium sulfate is insoluble in hydrochloric acid. When mixed, it forms a white precipitate of barium chloride and remains as solid particles in the solution.

What happens when barium sulfate is added with water?
When barium sulfate is added to water, it forms a suspension in which the particles do not dissolve in the water. This suspension is not soluble in water and can be filtered out. Barium sulfate is almost insoluble in water, which makes it useful for certain medical tests such as barium sulfate contrast studies.
How can you separate barium sulfate from potassium chloride?
One method to separate barium sulfate from potassium chloride is by precipitation. Adding a solution containing a soluble barium compound like barium nitrate will cause barium sulfate to precipitate out. The resulting mixture can then be filtered to separate the solid barium sulfate from the potassium chloride solution.
Barium chloride reacts sodium sulfate in aqueous solution to give soluble sodium chloride and insoluble barium sulfate how would you isolate the barium sulfate?
To isolate the barium sulfate, you would first filter the mixture to separate the solid barium sulfate from the remaining solution of sodium chloride. The collected barium sulfate can then be washed with distilled water to remove any impurities before drying it in an oven to obtain the pure compound.
Solutes that don't dissolve when warmed?
Some examples of solutes that do not dissolve when warmed include lead sulfate, barium sulfate, and strontium sulfate. These compounds have low solubility in water and do not readily dissolve with an increase in temperature.
Why is barium carbonate toxic while barium sulphate is not?
Barium sulfate is insoluble in water, while barium carbonate will dissolve. As barium carbonate dissolves in water, it dissociates, and the barium ions are freed. The barium ions are toxic, and that is the crux of the issue.
