How will we separate the mixture of sodium chloride and sand
Answers
Answer:
A mixture of sodium chloride and sand in water can be separated by the process of filtration and then by the process of distillation.
On filtering the solution, sand will remain on the filter paper while liquid will pass through it. This solution is than distilled. On distillation, water will evaporate and then get condensed and change into liquid state on cooling. This water will get collected in the beaker. while, salt will remain in the distillation flask as a residue.

Q. How will we separate the mixture of sodium chloride and sand?
Ans: First of all we should take mixture of send and sodium chloride. As we know that sodium chloride is a neutral salt which is formed by the chemical reaction of hydrochloric acid and sodium hydroxide. As we know that send contains silicon and oxygen. Now, we take this mixture in a China dish. Put half fill of water in a beaker and put the mixture present in a China dish. Put this mixer into the beaker which is half filled with water. By using the method of filtration, we can separate sand from this solution. The sand is deposited on the layer of a filter paper. Now, the pure solution please put it into the China dish for heating process. By using the method of crystallization we separate sodium chloride from water in a China dish. The water evaporates.
As a result we conclude that we can separate a mixture of sodium chloride and sand.
