Why common salt cannot purified by sublimation?
vapour pressure of common salt is higher... hence it cannot be sublimed...
How ammonium chloride is separated from common salt?
sublimation
Is KCL and NaCl is separated by sublimation?
Sodium chloride is not purified by sublimation.
What water salt or purified helps water?
purified
What water salt or purified helps plants grow?

By sublimation
What are the differences between the appearance of rock salt and purified salt?

How can you separate salt and camphor?
Camphor is a volatile solid i.e. its vapour pressure becomes equal to the atmospheric pressure much below the melting point. But, common salt is non-volatile. Hence, camphor may be very easily separated from common salt by a physical process, SUBLIMATION! props to yahoo answers
