1.	When an excess and a very dilute aqueous solution of KI is added to a very dilute aqueous solutions of silver nitrate, the colloidal particles of silver iodide which are associated with the Helmholtz double layer:-A. `AgIvdotsAg^(+)vdotsI^(-)`B. `AgIvdotsK^(+)vdotsNO_(3)^(-)`C. `AgIvdotsNO_(3)^(-)vdotsAg^(+)`D. `AGIvdotsI^(-)vdotsK^(+)`
Answer» Correct Answer - A 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^(-)`.
