Open in App
Solution
The correct option is D All of the above.
Adsorption is the accumulation of molecular species at the surface rather than in the bulk of a solid or liquid.
Application of adsorption:
1. Gas mask : Gas masks ( containing activated charcoal or mixture of adsorbents ) adsorb mostly impurities in the air.
It is usually used for breathing in coal mines to adsorb poisonous gases.
2. Removal of colouring matter from solutions: Raw brown sugar is passed over the charcoal bed to remove the brown colored matter and give white sugar crystals
Animal charcoal removes colours of solutions by adsorbing coloured impurities
3. Column chromatography: Chromatographic analysis based on the phenomenon of adsorption. It finds a number of applications in analytical and industrial fields.
Column chromatography is based on the different adsorbing tendencies of molecules toward silica (stationary phase).
