_______ is based on the difference in rates of adsorption of different substances on the surface of a suitable adsorbent.

• A. Filtration
• B. Choreography
• C. Chromatography
• D. Crystallization
  

Answer 1

The correct option is C

Chromatography

Chromatography is based on the difference in rates of adsorption of different substances on the surface of a suitable adsorbent.
It is basically a process of separating out different parts of chemical mixtures onto an adsorbent material that can then be individually analyzed because different parts are caught on the material at different rates. This process is used in forensic testing.
