Statement-1 :When AgNO3 is treated with ...

Statement-1 :When `AgNO_3` is treated with excess of Kl colloidal particles gets attracted towards anode.
Statement-2 :Colloidal particles adsorb common ions and thus become charged.

A

Statement-1 is True, Statement-2 is True, Statement-2 is a correct explanation for Statement-1

B

Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
D
`AgNO_3+underset(("excess"))(Kl)tounderset((PP'))(Agl)+KNO_3`
in excess of Kl common ion `I^(Theta)` is adsorbed preferentially on precipitate of AgI and becomes negatively charged colloidal particle `AgI//I^(-)`
