I didn't understand ths question and the approach to it... please explain
Solution -
Usually charge present on the colloid comes from adsorption of common ion from dispersion medium.so,
Millimole of Kl is maximum in option (2) so it is dispersion medium also, its Millimoles are=
50×2=100 millimoles.
so act as solvent and anion I- is adsorbed by the colloid Agl formed later. AgNO3 will act as dispersed phase.
AgNO3 + KI → AgI (colloid) + KNO3
So, option 2 is correct.
