in which of the following adsorption takesplace and why?
(i) silica gel placed in the atmosphere saturatated with water
(ii)anhydrous CaCl2 placed in the atmosphere saturated with water
(i) silica gel placed in the atmosphere saturatated with water will adsorb water it is an example of physical adsorption.
(ii)anhydrous CaCl2 placed in the atmosphere saturated with water-it is a bulk phenomenon(abosorption through out the caCl2) .It is not adsorption.
