Q. When dilute aqueous solution of ${AgNO}_{3}$(excess) is added to KI solution, positively charged sol of AgI is formed due to adsorption of of
A) ${NO}_{3}^{-}$
B) $O_{2}^{-}$
C) ${Ag}^{+}$
D) $K^{+}$
Explanation
(c)
When aqueous solution of ${AgNO}_{3}$ is added to KI solution, positively charged sol of AgI is obtained due to the adsorption of ${Ag}^{+}$ ions on AgI molecules.
