Q.6. To obtain 2.70 g of silver (at. mass 108) from an aqueous solution of it is required to pass
A. 4750 coulomb
B. 12062 coulomb
C. 2412.5 coulomb
D. 241.5 coulomb
Dear student ,
as we know that ; Ag+ + 1e- = Ag (1 mol or 108 gm)
and we also know that 1 mol e- carry 1 F (96500 C)
therefore ; it is given above that 108 gm Ag deposit by 1F
therefore 2.70 gm Ag requires 0.025 F or 2412.5 C
option C is correct
Regards
