Question

20. A mixture of iron nails, salt, oil and water is provided to you. Give stepwise methods to
separate each component from this mixture ?
Hint : (a) Iron nails-hand picking/magnet
(b) Oil-decantation
(c) Salt, water-evaporation and condensation​

Answer 1

Answer:

Iron nails can either be hand-picked or attracted to the magnet.

Oil can be removed by decantation method or using a separate funnel.

The salt solution can be evaporated.

In this, the water will be evaporated and the only salt will be left in the pan.
