Question

♡Silver nitrate (AgNO3) solution with sodium chloride (NaCl) forms a white

colloidal AgCl. Predict the charge on the colloidal AgCl when the amount of

AgNO3 is lower than the amount of NaCl.♡

(A) Neutral
(B) Positive

(C) Negative
(D) Zwitter ionic​..

Answer 1

Given:

Silver nitrate and Sodium chloride are made to react and silver chloride , Sodium nitrate is formed.

To find:

Charge on colloidal AgCl.

Solution:

As per the question, the amount of NaCl is greater than that of AgNO3.

This means that Cl- (chloride) ions become the common (excess) ion in the colloidal solution. Hence Chloride ions will be adsorbed on the surface of AgCl molecules.

The net colloid will be:

$\boxed{\red{\bold{\{AgCl\}{Cl}^{-}}}}$

Hence the colloidal solution will be negatively charged due to adsorption of a negative ion.
