how can make ammonium sulphate the in the laboratory from aqueous ammonia and sulphate ?

To make ammonium sulfate in the laboratory from aqueous ammonia and sulfate, you can follow these steps:

1. Start by preparing a solution of aqueous ammonia by dissolving ammonia gas in water. This can be done by bubbling ammonia gas through water until it is fully dissolved.

2. Next, prepare a solution of sulfate by dissolving a sulfate salt (such as sodium sulfate or magnesium sulfate) in water.

3. Mix the aqueous ammonia solution with the sulfate solution in a reaction vessel. The reaction between ammonia and sulfate ions will result in the formation of ammonium sulfate.

4. Allow the reaction mixture to stand for some time to ensure complete reaction and formation of the product.

5. Once the reaction is complete, you can isolate the solid ammonium sulfate by evaporating the water from the reaction mixture. This can be done by heating the mixture gently until all the water has evaporated, leaving behind the solid ammonium sulfate.

6. Finally, collect the solid ammonium sulfate and store it in a dry container for future use.

By following these steps, you can easily make ammonium sulfate in the laboratory from aqueous ammonia and sulfate.
