Question

How will you separate camphor, common salt and iron nails from their mixture ?

Answer 1

We will use the following methods to separate camphor, common salt and iron nails from their mixture:

Take the mixture and pour it in a beaker of water. On stirring,  salt will dissolve, while iron nails and camphor will not. Fold a fluted piece of filter paper and put it on the funnel. Then filter the mixture to another beaker. The salt solution will pass through and iron filings and camphor will remain on the paper. Put the filtrate into an evaporating dish and heat it over a Bunsen burner so that the water will evaporate. Eventually, salt will be left behind. Pass the magnet over the camphor and iron filings. The magnet will attract the iron, leaving behind camphor as residue.
