$AgNO_{3}$ added to $KI$ solution

Vedclass · Answer

(C) When $AgNO_{3}$ solution is added to $KI$ solution,$AgI$ is formed as a precipitate.$AgNO_{3(aq)} + KI_{(aq)} \rightarrow AgI_{(s)} + KNO_{3(aq)}$The precipitated $AgI$ particles preferentially adsorb $I^{-}$ ions from the excess $KI$ present in the dispersion medium,resulting in a negatively charged colloidal sol $(AgI/I^{-})$.Conversely,when $KI$ is added to $AgNO_{3}$ solution,$AgI$ particles adsorb $Ag^{+}$ ions,forming a positively charged colloidal sol $(AgI/Ag^{+})$.$FeCl_{3}$ in hot water forms a positively charged $Fe_{2}O_{3} \cdot xH_{2}O$ sol,and $Al_{2}O_{3} \cdot xH_{2}O$ is also typically positively charged.

The sol given below with negatively charged colloidal particles is:
