Answer 1

The following procedure can be used to separate salt, sand, oil, and water:

1. Decantation:

Because oil floats on water (it is insoluble in water), it may be readily decanted.

2. Filtering:

Filter the mixture, and the sand (which is insoluble in water) will be separated from the water, leaving only the salt solution.

3. Evaporation:

The salt can be separated from the salt solution by evaporating it.
