A mixture of camphor and KCl can be separated by which of the followin...
Camphor is scientifically known as Cinnamomum Camphor.
  • It is a combustible translucent white solid which has a piquant smell and sour taste.
  • Camphor belongs to a group of organic compounds defined as terpenoid ketones.
  • Potassium Chloride is an important metal halide. Which is an essential electrolyte source for our body.
  • Each KCl molecule contains one potassium cation and one chloride anion.
  • Camphor is a white waxy solid which melts about 178°C−179 °C. Whereas KCl is an odorless white crystalline solid with a melting point of 770 °C.
  • Usually, we know that when we heat a solid they melt first to become a liquid. On further heating, the liquid boils and enters into the vapour phase. But some solid substances will directly change into gases from solid-state on heating.
For example camphor, Naphthalene substances are called sublime.
  • So this process of conversion is known as sublimation.
  • Sublimation occurs because we know that all substances are made of atoms and molecules. These particles are held together by a force of attraction. If the force of attraction between the particles is weak then the particles can separate easily.
  • So in camphor, the molecules are held together by weaker force so they can simply evaporate on heating without melting.
  • In camphor, the molecules are held together by weak attractive force, which means that even at moderate temperature the molecule of camphor can escape and spread everywhere.
  • Here given is camphor and KCl mixture, in which camphor is a solid sublimate component and KCl is a non-sublimate component. To separate these mixtures we can use the sublimation process. The vapours of camphor can be collected and cooled down.
Note-
  • The changing of solid directly into vapours on heating, and vapours directly into solid on cooling is called sublimation.
  • The solid substance which undergoes sublimation is called sublime.
  • And the solid substance obtained by cooling the vapor is known as sublimate.
