Answer:
There are various applications of
adsorption in chemical analysis.
Some of which are as follows
(i) In thin layer
chromatography the lower adsorbing particles comes out readily while another
having higher adsorbing tendency comes out later. On this basis compounds are
separated or analysed.
(ii) In adsorption indicators
Surface of certain precipitate has an ability to adsorb some dyes to produce a
characteristic colour e.g., AgX adsorbs eosin dye and thereby producing a
characteristic colour at the end point.
(iv) In qualitative analysis
Specific material has specific adsorption tendency so particular ion can be
identified very easily.
(v) In the separation of inert gases
Different inert gases are adsorbed to different extents at different
temperatures on coconut charcoal. This forms the basis of their separation from
a mixture.
