An aqueo solution contains 2 solutes A&B.A is soluble in hexane and B is not.Hexane is liquid at room temperature and does not mix with water.The density of hexane at room temperature is 0.7g/dm3.Describe givig full practical details how you would produce a pure sample of solute A.

Answered above several times.

To produce a pure sample of solute A from the aqueous solution containing both solutes A and B, you can follow the steps below:

1. Begin by pouring the aqueous solution into a separating funnel. Make sure to discard the organic layer containing hexane that separates from the water layer at the bottom.

2. Once you have only the water layer in the separating funnel, carefully transfer it to a clean beaker.

3. Now, add hexane to the beaker containing the water layer. Since hexane is immiscible with water, it will form a separate layer on top.

4. Gently shake or stir the contents of the beaker for a few seconds to allow mixing of solute A with hexane.

5. Let the beaker sit undisturbed for some time. As solute A is soluble in hexane, it will dissolve into the hexane layer, while solute B remains in the water layer.

6. After sufficient time has passed to allow for complete separation, you can carefully pour the hexane layer containing solute A into another clean container, while leaving behind the water layer containing solute B.

7. To ensure the separation is thorough and minimize any potential contamination, you can repeat the extraction process by adding fresh hexane to the water layer in the original beaker. Repeat the shaking, settling, and separation steps to obtain additional pure solute A.

8. Once you have the desired amount of solute A in the collected hexane layer, transfer this mixture to an evaporating dish or flask.

9. Place the evaporating dish on a heat source, such as a hot plate or Bunsen burner, and gently heat the mixture. The low boiling point of hexane (approximately 69°C) will allow it to evaporate quickly, leaving behind the pure solute A.

10. Finally, collect the pure solute A from the evaporating dish or flask, which can be stored in a suitable container for further analysis or use.

Remember, it is crucial to handle flammable solvents like hexane with care and work in a well-ventilated area to ensure safety.
