When a steady current of was passed through two electrolytic cells A and B containing electrolytes and connected in series, of were deposited at the cathode of cell B. How long did the current flow ? What mass of was deposited at cathode of cell ?
[Atomic mass :]
Given-
current =
deposited = 2 g
m=ZxIxt
2 = 63.5 x 2 x t/2x96500
t = 3039.4 s
m1/m2 = eq wt 1/eq wt 2
2 / m2 = (63.5/2) / (65/2)
Hence, m2 = 2.05 g
