Suggest how you could obtain solid sodium chloride from a mixture of sand chloride?

To obtain solid sodium chloride from a mixture of sand and chloride, you can use the following steps:

1.Dissolution:

- Place the mixture of sand and chloride in a container.

- Add water to the container, ensuring it is enough to dissolve the chloride.

- Stir the mixture until the chloride is completely dissolved, and the sand particles settle at the bottom.

2.Filtration:

- Set up a filtration system using a funnel and filter paper.

- Place the funnel over a clean container.

- Pour the mixture from step 1 onto the filter paper, allowing the liquid (containing the dissolved chloride) to pass through while the sand particles are retained on the filter paper.

3.Evaporation:

- Collect the filtrate from step 2, which contains the dissolved chloride.

- Transfer the filtrate to a clean container suitable for heating.

- Place the container over low heat and allow the water to evaporate.

4.Crystallization:

- As the water evaporates, the sodium chloride will start to crystallize and form solid crystals.

- Continue heating until all the water has evaporated, and you are left with solid sodium chloride crystals.

5.Separation:

- Once the evaporation is complete, let the container cool.

- The solid sodium chloride crystals should have formed at the bottom of the container.

- Carefully pour or scrape the sodium chloride crystals out of the container, separating them from any remaining impurities or sand particles.

6.Drying:

- Spread the sodium chloride crystals on a clean surface or a tray.

- Allow them to dry completely, ensuring there is no remaining moisture.

By following these steps, you can successfully obtain solid sodium chloride from a mixture of sand and chloride.
