Which of the following sets of operation will completely separate a mixture of sodium chloride, sand and iodine?
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 \(\to\) Filtration \(\to\) Evaporation \(\to\) Sublimation.
