how to saprate glass powder + iodine + sugar.
Answers
Answer:
Dissolve the mixture in water. Salt would dissolve (I assume salt is sodium chloride). Filter out the glass and iodine and dry them. Evaporate the water to get the salt. Now dissolve the glass and iodine in ethanol or chloroform. Iodine dissolves leaving the glass which can be removed by filtering. The iodine can be recovered by evaporation of the ethanol or chloroform.
The basic idea in such a problem is to identify a solvent which would dissolve only one of the components or all but one of the components, then filter to get the remaining components. This process can be repeated till you can separate all the components. You can also use some specific property of the components (eg in this case, iodine can undergo sublimation but it is a rather energy intensive process and messy).
