Question

A solution of copper sulphate containing sand grains can be purified by using _________technique.

Answer 1

Separation of copper sulphate containing sand grains:

• We can use the filtration technique for separating sand and grains from the solution of copper sulfate.
• The solution will easily pass through the filter paper while sand and grains will not pass the filter paper and be left behind.

Filtration:

• A process by which insoluble solute particles can be removed from a solution by using filter paper is known as filtration.
• A filter paper is a special type of paper that has pores that are tiny enough to let only liquids pass through it.

Therefore, A solution of copper sulphate containing some sand grains can be purified by using the filtration technique.
