Assertion: A sol of `As_(2)S_(3)` prepared by the action of `H_(2)S` on `As_(2)O_(3)` is negatively power.
Reason: It is due to the presence of `S^(2-)` ions in the diffused layer.

A

Statement-1 is True, Statement-2 is True, Statement-2 is a correct explanation of Statement-1.

B

Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation of Statement-1.

C

Statement-1 is True, Statement-2 is False.

D

Statement-1 is False, Statement-2 is Ture.

Text Solution

Verified by Experts

The correct Answer is:
C
Correct Statement-2, it is due to adsorption of `S^(2-)` ions on the surface of the colloidal particles and `H^(+)` ions in the diffused layer.
