Question

One desires to prepare a positively charged sol of silver iodide. This can be achieved by (A) adding small amount of AgNO3 solution to KI solution in slight excess (B) adding small amount of KI solution to AgNO3 solution in slight excess (C) mixing equal volumes of equimolar solutions of AgNO3 and KI (D) None of these

KI+ AgNO3 (slight excess) arrow AgI + KNO3 AgNO3 arrow Ag+ + NO3- AgI(s) + Ag+ xrightarrow [AgI] Ag+

Q. One desires to prepare a positively charged sol of silver iodide. This can be achieved by

adding small amount of $A g N O_{3}$ solution to KI solution in slight excess

adding small amount of KI solution to $A g N O_{3}$ solution in slight excess

mixing equal volumes of equimolar solutions of $A g N O_{3}$ and KI

None of these

$K I + A g N O_{3}$ (slight excess) $\to A g I + K N O_{3}$
$A g N O_{3} \to A g^{+} + N O_{3}^{-}$
$A g I (s) + A g^{+} A A g I g^{+}$

Q. One desires to prepare a positively charged sol of silver iodide. This can be achieved by

adding small amount of AgNO3​ solution to KI solution in slight excess

adding small amount of KI solution to AgNO3​ solution in slight excess

mixing equal volumes of equimolar solutions of AgNO3​ and KI

None of these

KI+AgNO3​ (slight excess) →AgI+KNO3​ AgNO3​→Ag++NO3−​ AgI(s)+Ag+AAgI​g+

adding small amount of $A g N O_{3}$ solution to KI solution in slight excess

adding small amount of KI solution to $A g N O_{3}$ solution in slight excess

mixing equal volumes of equimolar solutions of $A g N O_{3}$ and KI

$K I + A g N O_{3}$ (slight excess) $\to A g I + K N O_{3}$
$A g N O_{3} \to A g^{+} + N O_{3}^{-}$
$A g I (s) + A g^{+} A A g I g^{+}$
