Adsorption

Sharada

31/05/2017 0 0

Solid surface has the tendency to attract and retain the molecules of the phase with which it comes in contact.These molecules remain only at the surface and do not go deeper into the bulk.

The process in which molecular species are accumulated at the surface rather than in the bulk of a solid or liquid phase is termed as adsorption, example - water vapours on silica gel ,H2 ,O2,NH3 on activated charcoal.
