which apparatus is better to separate salt and sand explain
Answers
It is easy to separate sand and water by filtering the mixture. Salt can be separated from a solution through evaporation. The water can also be recovered as well as the salt if the water vapour is trapped and cooled to condense the water vapour back into a liquid. This process is called distillation.

In this class experiment, students separate a mixture of sand and salt, illustrating the fundamental means of separating a mixture of an insoluble material from one that is soluble
This is a very straightforward experiment. It can be carried out individually or in groups of two. Pupils must stand up during heating activities and beware of hot salt spitting when evaporation is almost complete.
