Answer» Solution :(a) Principle: This method is based upon the differential adsorption of the various components of a mixture on a suitable adsorbent to DIFFERENT degree. (b) Adsorbent: The compound adsorbed on which is CALLED adsorbent. E.g. silica gel and alumina Adsorbent is a stable so it is called stationary phase. (C ) Mobile phase : In adsorbed (stationary phase) which is liquid SOLVENT pass through it which one is known as mobile phase. (d) Adsorbate: The compound or the mixture of compound which is kept in adsorbent is called adsorbate. It REMAIN seen suitable solvent then migrate and separate in stationary phase |
