You have been provided with a mixture of: salt, sand, oil and water. Write down the steps to separate the individual components. Draw diagrams to support your answer.

Answer 1

Answer:

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 out.
