How do will you separate a mixture of sandiron filingsnapthelene and sodium chloride name the procedure have used?

Separating a mixture of sand, iron filings, naphthalene, and sodium chloride

The following procedure can be used to separate the mixture:

1. Physical separation:

- Sieving: Use a sieve to separate the sand particles from the rest of the mixture. The sand particles will pass through the sieve, while the larger iron filings, naphthalene flakes, and sodium chloride crystals will be retained on top.

2. Magnetic separation:

- Use a magnet to separate the iron filings from the remaining mixture. The iron filings will be attracted to the magnet, while the naphthalene and sodium chloride will not.

3. Sublimation:

- Place the remaining mixture (naphthalene and sodium chloride) in a sublimation apparatus. Heat the mixture gently until the naphthalene sublimes (converts from a solid to a gas). The naphthalene vapors will condense back into a solid in a cooled part of the apparatus, leaving behind the sodium chloride.

4. Crystallization:

- Dissolve the sodium chloride in water to form a saturated solution. Heat the solution until all the sodium chloride is dissolved. Allow the solution to cool slowly to room temperature. As the solution cools, the sodium chloride will crystallize out of the solution. Filter the crystals to separate them from the water.

5. Drying:

- Dry the separated sand, iron filings, naphthalene, and sodium chloride crystals to remove any residual moisture.

By following this procedure, you can successfully separate the mixture of sand, iron filings, naphthalene, and sodium chloride into its individual components.
