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.
i.e.,
So for 6000 C charge total nickel deposition will be:-
or
Hence 1.825 g Ni will be deposited in the given conditions.
