Question

Write about adsorption from solutions?

Answer 1

Answer:

Explanation:

Charcoal pieces are added to the acetic acid solution. Some of the acetic acid molecules adsorb on charcoal. This depends upon,

• Nature of adsorbate
• The surface area of the adsorbent  
• Temperature  
• Concentration

Answer 2

Explanation:

Solids also adsorb from solutions. For example, when a solution of acetic acid in water is mixed with charcoal, some of the acid is adsorbed by the charcoal.

Characteristics of adsorption from the solution phase-

Adsorption decreases with increase in temperature.

More surface area more is the rate of adsorption.

Adsorption also depends on concentration of solute in a solution.

Adsorption also depends on nature of adsorbate and nature of adsorbent
