Answer» `AgIvdotsAg^(+)vdotsI^(-)` `AgIvdotsK^(+)vdotsNO_(3)^(-)` `AgIvdotsNO_(3)^(-)vdotsAg^(+)` `AGIvdotsI^(-)vdotsK^(+)` Solution :When KI solution is added to `AgNO_(3)` solution, positively CHARGED SOL results due to adsorption of `Ag^(+)` from DISPERSION medium forming `AgI//Ag^(+)` acquired a positive charge. This layer ATTRACTS counter ions from the medium forming a second layer as `AgI//Ag^(+)//I^(-)`.
