A metal is known to form fluoride MF 2 . When 10A of electricity is passed through a molten salt for 330 sec., 1.95g of metal is deposited. Find the atomic weight of M. What will be the quantity electricity required to deposit the same mass of Cu from CuSO 4 ?
Text Solution
Verified by ExpertsThe correct answer is:
A
A = 114 , Q = 5926.8C.
Sol. v.f. of metal = 2.
w = Zit.
1.95 = 
it = 
M = 114 g.
w = 
⇒ 1.95 = 
⇒ it = 5926.77 C.
