A constant current of 4.5 amperes to produce 15 g of chromium from chromium iii sulfate solution is t = 5.15 hours.
Calculation:-
From faraday Law
w---weight= 15g
E ---equivalent wt of Cr(III) =17.33
i----current = 4.5amp
t--- time =?
W = ( E x i x t )/ 96,500
15 = (17.33 x4.5 x t) /96,500
t = 18561.26 sec
t = 309.35min
t = 5.15hours
