When dilute aqueous solution of `AgNO_3` (excess) is added to KI solution, positively charged sol of Agl in formed due to adsorption of

A

`NO_(3)^(-)`

B

`O_(2)^(-)`

C

`Ag^(+)`

D

`K^(+)`

Text Solution

Verified by Experts

The correct Answer is:
C
When excess of `AgNO_(3)` is added, precipitate of formed changes into positively charged colloidal parts due to adsorption of `Ag^(+)` ions `(AgI:Ag^(+))`
