$Ag^{+}$

Vedclass · Answer

(B) When $AgNO_3$ is added in excess to $KI$ solution,the $AgI$ precipitate is formed. Since $AgNO_3$ is in excess,the $Ag^{+}$ ions are present in the dispersion medium. The $AgI$ particles preferentially adsorb the common ion from the dispersion medium. Thus,$AgI$ particles adsorb $Ag^{+}$ ions from the solution,resulting in the formation of positively charged colloidal particles: $[AgI]Ag^{+}$.

When a dilute aqueous solution of $AgNO_3$ (in excess) is added to a solution of $KI$,the positively charged $AgI$ particles are formed due to the adsorption of which ions?
