How would you test for potassium and sulfate ions in the alum?
To test for potassium ions, you can use a flame test by heating a sample of the alum on a looped wire in a Bunsen burner flame; potassium ions produce a lilac flame color. For sulfate ions, you can add a few drops of barium chloride solution to a solution of the alum; a white precipitate (barium sulfate) forms if sulfate ions are present.
What do you get if you add sodium sulfate to barium chloride?
When you add sodium sulfate to barium chloride, a white precipitate of barium sulfate forms. This is due to the reaction between sodium sulfate and barium chloride, which forms insoluble barium sulfate.
Does the mass of water increase when you add copper sulfate?
The mass of water does not increase when copper sulfate is added to the water, unless the copper sulfate is hydrated. The mass of the mixture of water and copper sulfate, of course, does increase.
Separate chalk from a mixture of chalk and copper sulfate solution?
To separate chalk from a mixture of chalk and copper sulfate solution, you can add water to dissolve the copper sulfate, leaving behind the chalk. The water-soluble copper sulfate will form a blue solution, allowing you to filter out the chalk residue, which is insoluble in water.
- What would happen to the anhydrous cupric sulfate if you added water to it?
Anhydrous cupric sulfate would form hydrated copper(II) sulfate when water is added to it. This process is exothermic and the anhydrous crystals would dissolve as the water molecules bond with the copper sulfate molecules to form a hydrated crystal structure.
How do you test for barium ions in a solution?
Add a sulfate solution: BaSO4 precipitates!
How can you test a solution for the presence of ba ions?
Add a sulfate solution: BaSO4 precipitates!

How to add aluminum sulfate to soil effectively for optimal results?
To add aluminum sulfate to soil effectively for optimal results, first test the soil pH to ensure it is suitable for the addition of aluminum sulfate. Then, apply the aluminum sulfate evenly over the soil surface and water it in thoroughly. Monitor the soil pH regularly and adjust the application as needed to maintain the desired levels.
What happens when you add morphine sulfate with zinc sulfate?
Nothing, they do not react
How do you drop Mercury from mercuric nitrate?
To drop Mercury from mercuric nitrate, add a reducing agent such as elemental zinc or copper. The reaction will result in Mercury being reduced from the mercuric state to metallic Mercury. This can be separated by filtration.
How to prepare of 0.1N mercuric chloride?
To prepare 0.1N mercuric chloride solution, you would dissolve 2.72 grams of mercuric chloride (HgCl2) in 1 liter of water. 0.1N means the solution contains 0.1 moles of mercuric chloride in 1 liter of solution. Be cautious when working with mercuric chloride as it is toxic and should be handled with proper safety precautions.
Is Na2SO4 soluble in water?
Yes, sodium sulfate is water soluble. Many sulfates are soluble in water. A notable exception is barium sulfate, whose insolubility forms the basis of a test for the presence of sulfate ions. Add barium chloride to a solution containing sulfate ions. The white barium sulfate precipitate is a positive test for sulfate ions.
What do you get if you add sodium sulfate to barium chloride?
When you add sodium sulfate to barium chloride, a white precipitate of barium sulfate forms. This is due to the reaction between sodium sulfate and barium chloride, which forms insoluble barium sulfate.
Does the mass of water increase when you add copper sulfate?
The mass of water does not increase when copper sulfate is added to the water, unless the copper sulfate is hydrated. The mass of the mixture of water and copper sulfate, of course, does increase.
What is the gas formed when you add zinc to copper sulfate?
When you add zinc to copper sulfate, zinc displaces copper in the compound and forms zinc sulfate. As a result, copper is released as a solid, and no gas is produced in this reaction.
How do you test for presence of Barium and Iodine in aqueous solution?
To test for the presence of barium in an aqueous solution, you can add a sulfate solution, such as barium sulfate, which will form a white precipitate if barium is present. For iodine, you can add a few drops of starch solution; if iodine is present, it will produce a blue-black color due to the formation of the iodine-starch complex. Both tests should be conducted under controlled conditions to ensure accurate results.
