In order to form a negatively charged colloidal sol on addingAgNO3solution 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 MAgNO3+ 40 mL of 0.1 M KCl
m moles ofAgNO3=50×0.1=5
m moles ofKI=50×0.2=10
KI is in excess
So,I−is adsorbed on AgI sol
