(2) 12 : 1
Explanation:
Given: The same current is passed for the same period through molten Al2(SO4)3 and aqueous AgNO3.
Find: Ratio of the weights of Ag and Al deposited at the cathode.
Solution:
Ratio of the weights of Ag and Al deposited at the cathode = Mass of Ag / mass of Al
= Equivalent weight of Ag / Equivalent weight of Al
= 108 / 9
= 12 : 1
Option 2 is the answer.
