Asked by Golekha Chandra Biswal | 18 May, 2012, 09:01: PM
Expert Answer
Dissolve the three substances in water
Iron filling can be removed through a magnet. Mix the other two substances salt and sand with water. Run the mixture through a filter paper. The sand will be separated as it will come on the paper.
Boil the water until it evaporates, turns into a gas and runs through tubes to a separate chamber. Salt will get deposited.
Hence, all the three can be separated.
