Prepare a mixture of salt and sand. Put about 2 mL of the mixture in a test-tube. Add 5 mL
water and shake until all the salt has dissolved. Pour the contents of the tube into a filter
paper in a funnel over an evaporating basin. Wash the test-tube with water and add this to
the filter paper. The sand will remain on the filter paper and may be dried and collected.
The salt can be recovered from the filtrate by warming the evaporation basin to drive off
the water.
