Question

Crystals of pure copper sulphate are separated from the solution by :

• A. condenstaion
• B. distillation
• C. solidification
• D. filtration

Answer 1

The correct option is D filtration

Crystal of pure copper sulphate can be obtained from an impure sample by re-crystallization. In re-crystallisation of copper sulphate the impure sample is dissolved in water, heated, and then cooled which then later forms pure crystals. These copper sulphate crystals are then separated by the filtration method.
