Question

When in excess, a very dilute aqueous solution of $$KI$$ is added to a very dilute aqueous solution of silver nitrate, the colloidal particles of silver iodide, associated with the Helmholtz double layer, are


A
AgI:Ag+:NO3
loader
B
AgI:K+:NO3
loader
C
AgI:NO3:Ag+
loader
D
AgI:I:K+
loader

Solution

The correct option is B $$AgI : I^{-} : K^{+}$$
The Helmholtz double layer contains a layer of opposite charge on the surface of colloidal particles.

$${AgNO_{s} + \underset{excess}{KI}} \rightarrow AgI + KNO_{3}$$

$$AgI + KI \rightarrow AgI : I^{-} : K^{+}$$.
