When a finely divided active carbon or clay is stirred into a dilute solution of a dye, we observe that the intensity of colour in the solution is decreased on account of

A

adsorption

B

adsorption

C

desorption

D

sorption

Text Solution

Verified by Experts

The correct Answer is:
B

This is because the dye is adsorbed solid surface. Similary, when a finely divided is exposed to a gas at some pressure, the pressure decreases noticeably because the gas is adsorbed on the solild surface.
