Question

Which of the following represents the correct statement?

विकल्प

• Evaporation of water results in the formation of salts.

• The salt obtained during crystallisation is pure and its crystals are large.

• The shape of crystals can be seen clearly after crystallisation.

• Large crystals of pure substances cannot be formed from their solution.

Answer 1

Evaporation of water results in the formation of salts.

Explanation:

Salt can be obtained by the evaporation of sea-water. The salt obtained during crystallisation is not pure and its crystals are small. After crystallisation, the shape of the crystals cannot be seen clearly. Large crystals of pure substances can be formed from their solutions.
