3.15 A solution of is electrolysed between platinum electrodes using a current of amperes for minutes. What mass of Ni is deposited at the cathode?
We are given:
I = 5A
and t = 20(60) = 1200 sec.
So total charge = 5(1200) = 6000 C.
The equation for nickel deposition will be:-
Thus, from 2F charge 58.7 g of nickel deposition takes place.
So for 6000 C charge total nickel deposition will be:-
Hence 1.825 g Ni will be deposited in the given conditions.
