Solution
The correct option is A crystallisation
Crystallisation is a technique used to separate out dissolved salts as crystals, from their saturated solutions.
- This involves heating the saturated solution at high temperature and then cooling it down.
- This leads to gradual formation of crystals.
- The salts that crystallize out are mostly pure and free of impurities.
Salts like copper sulphate can be purified by this method.
Filtration is a separation technique used mostly to separate the solute particles of a suspension.
The conversion of a liquid into gas is called vapourisation.
