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 giving an activity along with the diagram.
Solution
We can separate salt, sand, oil and water with the following method -
- Decantation : Because oil floats on water (it is insoluble in water), it is simple to decant.
- Filtration : Filter the mixture to separate the sand from the water (sand is insoluble in water), leaving just the salt solution.
- Evaporation : Salt can be separated from a solution by evaporating it.
