Question

Iodine can be separated from a mixture of Iodine and Potassium Chloride by

Answer 1

the process of
sublimation

Answer 2

Explanation:

When we heat a mixture of Iodine and Potassium Chloride then iodine readily vapourizes and gets deposited over a cool surface.

As the melting point of iodine is less that the meltling point of KCl, therefore, iodine readily changes from solid to vapour phase. As a result, iodine gets separated from a mixture of iodine and potassium chloride.

This property of a solid changing directly into gaseous phase is known as sublimation.

Thus, iodine can be separated from a mixture of Iodine and Potassium Chloride by sublimation.
