question_answer

When dilute aqueous solution of \[\text{AgN}{{\text{O}}_{\text{3}}}\](excess) is added to KI solution, positively charged sol of \[\text{AgI}\]is formed due to adsorption of:

A) \[NO_{3}^{-}\]                 

B)  \[O_{2}^{-}\]

C)  \[A{{g}^{+}}\]  

D)         \[{{K}^{+}}\]

Correct Answer: C

Solution :

When aqueous solution of \[\text{AgN}{{\text{O}}_{\text{3}}}\]is added to solution, positively charged sol of \[\text{AgI}\]is obtained due to the adsorption of \[\text{A}{{\text{g}}^{+}}\]ions on \[\text{AgI}\]molecules.
