Answer

In order to form a negatively charged colloidal sol on adding AgNO3 solution into KI solution, KI should be in excess.

Among all options, KI is in excess in option B as shown:

50 mL of 0.1 M AgNO3 + 40 mL of 0.1 M KCl

m moles of AgNO3=50×0.1=5

m moles of KI=50×0.2=10

KI is in excess

So, I− is adsorbed on AgI sol
