Answer 1

Answer:

Explanation:

1) Pour the mixture in a container having water and stir well. The salt will dissolve in it.

2) Now pass the mixture (aqueous) into another container using a sieve. The sand and the solution will pass through sieve and the pebbles will get separated out.

3) Then pass the salt solution having sand through a filter paper into another container using a funnel with a Filter paper. Thus, the sand will get separated out.

4) Finally take the remaining solution and heat it till all the water vaporises and the salt remains in the container.
