Question

Rohan mixed water , salt and sand while playing now he wants to separate them . Could you help him ?

Answer 1

First Rohan should apply the filtration process to separate the sand out of the mixture.
Then once the sand is removed, he should go for evaporation of water and hence salt will remain behind.
Hope that helps you ✌️

Answer 2

Answer:

Decantation and evaporation can be used to separate salt, sand and water from the mixture.

Explanation:

First for the separation of sand, salt and water mixture, decantation and evaporation can be used.

Decantation will separate sand from salt and water. Decantation is separation of liquid from solid and other non-mixing liquids, by removing the liquid layer from the top of the solid or liquid below. The process will be followed by tilting the liquid after pouring out the top layer.

Sand stays in the original vessel, whereas salt and water is transferred to new vessel.

Evaporation will separate salt from water. Water is evaporated but vapor can be collected and cooled down to water and salt is left behind. Salt crystal can be collected by crystallization method.
