Question

If we add dilute aqueous solution of KI dropwise to AgNO 3 aqueous solution, the AgI colloid formed will have (A) negatively charged (B) positively charged (C) neutral (D) nothing can be predicted

AgNO 3(a q)+ KI (a q) arrow underset textcolloide[ AgI] I -+ KNO 3 AgI will absorb I- from KI electrolyte to form [AgI]I- Therefore, it is negatively charged.

Q. If we add dilute aqueous solution of $K I$ dropwise to $A g N O_{3}$ aqueous solution, the $A g I$ colloid formed will have

negatively charged

positively charged

neutral

nothing can be predicted

$A g N O_{3 (a q)} + K I_{(a q)} \to colloide [A g I] I^{-} + K N O_{3}$

AgI will absorb $I^{-}$ from KI electrolyte to form $[A g I] I^{-}$ Therefore, it is negatively charged.
