Question

Tyndall effect. Differentiate between adsorption and absorption

Answer 1

Answer:

Tyndall effect :--when a beam of light is passed through a colloidal solution and viewed perpendicular to the path of incident light, the path of beam is illuminated by a bluish light this phenomenon is known as Tyndall effect.

Difference between adsorption and absorption are as follows :-

Adsorption :-

• it is the surface phenomenon i. e, it occurs only at the surface of the adsorbent
• in this phenomenon the concentration on the surface of adsorbent is different from that in the bulk
• its rate is High in the beginning and then decreases till equilibrium is attained.

Absorption :-

• it is a bulk phenomenon i. e, occurs throughout the body of the material
• In this phenomenon the concentration is same throughout the material
• its rate remain same throughput the process.

Answer 2

Answer:

Explanation:

absorprion is only possible in our bodyand adsorption only possible in other
