how will you seprate the sand, salt, iron nail

Dear student,

Iron nails can be easily separated form salt and sand by using magnet. Take a magnet close to the mixture, it will attract all the iron nails towards it.
Now we are left with salt and sand. Dissolve the mixture of salt and sand in water and then filter it . Salt dissolves in water and sand will be left out in filter paper. Now heat the water solution of salt , all water will evaporate and we get the salt crystals.

Regards
