Question

method to separate iodine & sand mixture​

Answer 1

Answer:

The mixture of iodine and sand can be separated by the process of sublimation

Iodine undergoes sublimation i.e changes directly from solid to gas, when heated.

So when the mixture of iodine and sand is taken in a China dish and keeping an closed inverted funnel on it, the iodine changes into vapour, gets solidified and will be collected on the walls of the funnel.
