Question

How will you separate a mixture of chalk and common salt into it's components?

Answer 1

• Decantation can be used here since common salt is soluble in water and chalk does not
• Chalk will remain as an insoluble part which can be separated by decantation by pouring the insoluble contents into another beaker.
• Dissolved common salt can be separated by the evaporation technique

Hence, decantation can be used to separate the mixture of chalk and common salt
