Which of the following sets of operation will completely separate a mixture of sodium chloride, sand and iodine?
addition of water, filtration, evaporation to dryness and sublimation
filtration, evaporation to dryness, addition of water and sublimation
sublimation, filtration, evaporation and addition of water
sublimation, addition of water, filtration and evaporation to dryness
Correct answer is A
Process:
Add water to the mixture and then filter. The resultant is a salt solution as your filtrate and a mixture of iodine and sand as your residue. Evaporate the filtrate to dryness to get your sodium chloride (salt). Heat the residue to sublime the iodine from the sand.
Addition of water → Filtration → Evaporation → Sublimation.
