Question

) You are provided with a mixture of salt, sand, oil and
water. Write the steps involved for the separation of
salt, sand and oil from the mixture by using an activity
along with the diagram.

Answer 1

Answer:

Sand will sink at the bottom, Salt will dissovle in water, so filter this solution thereby separating the sand particles then let the water evaporate to reclain the water

Answer 2

Explanation:

We can separate salt, sand, oil, and water with the following method -

1. Decantation - 

Oil floats on water (oil is insoluble in water), so it can be decanted easily.

2. Filtration-

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

3. Evaporation-

The salt solution can be evaporated, by this, the salt will separate.
