Question

suppose you were given a sample of iodine crystals, a sampleof antimony, and a sample of mixture of iodine and antimony thathad been ground together to form a fine powder of uniformconsistency. look up the physical and chemical properties ofboth iodine and antimony. then list the properties of eachelement that you believe would be useful in separating andrecovering them from the mixture. on the basis of theseproperties, devise a procedure to separate the two elements fromthe mixture and recover the separate element.

Explanation / Answer

Sublimation:

Sublimation means change of state of solid to direct gas phase

Sublimation is the best procedure to separate these two elements; I2 and antimony from the mixture because I2 is sublimable thus it will change into vapor state directly from solid when heated slightly the mixture. Now we can collect the I2 vapor which on cooling give pure I2
