Current Question (ID: 18399)

Question:

$\text{Water vapours can be both adsorbed and absorbed by respectively?}$

Options:

1. $\text{Silica gel and CaCl}_2$
2. $\text{Chalk and CaCl}_2$
3. $\text{CaCl}_2 \text{ and Silica gel}$
4. $\text{CaCl}_2 \text{ and Chalk}$

Solution:

$\text{Adsorption is a surface phenomenon and absorption is a bulk phenomenon.}$ $\text{Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid, or dissolved solid to a surface.}$ $\text{This process creates a film of the adsorbate on the surface of the adsorbent.}$ $\text{Absorption is a physical or chemical phenomenon in which atoms, molecules or ions enter some bulk phase: gas, liquids or solid material.}$ $\text{Water vapour is absorbed by anhydrous calcium chloride while it is adsorbed by silica gel.}$
