[AgI]IΘ colloid will be formed only when the iodide ion is present in excess.

Q. Which of the following mixture will lead to the formation of negatively charged colloid $[A g I] I^{Θ}$ ?

$50$ ml of $0.1 M A g N O_{3} + 50$ ml of $0.1 M K I$

$50$ ml of $0.1 M A g N O_{3} + 50$ ml of $0.2 M K I$

$50$ ml of $0.2 M A g N O_{3} + 50$ ml of $0.1 M K I$

$50$ ml of $0.2 M A g N O_{3} + 50$ ml of $0.2 M K I$

$[A g I] I^{Θ}$ colloid will be formed only when the iodide ion is present in excess.
