Question

Common salt , iodine and chromium granules we're accidentally mixed up.techniques to separate

Answer 1

First you heat the mixture and iodine will sublimate. The iodine gas can be deposited somewhere else. Then you can mix the remaining mixture in water. The common salt will dissolve and the chromium will just stay there. You can collect the granules by some physical method and evaporate the water to get the common salt.
