Pridenet p printing Print calculator-Periodic Table 3 of 10 apling Learning cetan learning Purification of nickel can be achieved by electrorefining nickel from an impure nickel anode onto a pure nickel cathode in an electrolytic cell. How many hours will it take to plate 15.5 kg of nickel onto the cathode if the current passed through the cell is held constant at 42.0 A? Assume the nickel in the electrolytic solution is present as Ni2 NumberExplanation / Answer
W = MCt/ZF
Ni^2+ (aq) + 2e^- -------------> Ni(s)
Z = 2
M = 58.69g/mole
F = 96500c
C = 42A
W = 15.5Kg = 15500g
W = MCt/ZF
t = WZF/MC
= 15500*2*96500/58.69*42
= 1213600seconds
= 1213600/3600 = 337.1h >>>>answer
