A solution is prepared by dissolving 32.0 g of NiSO₄ in water. What current would be needed to deposit all of the nickel in 5.0 hours?

Question

Quizplus · Accepted Answer

To find the current needed, first calculate the moles of NiSO₄, then the moles of Ni. Use Faraday's laws of electrolysis: 1 mole of Ni requires 2 Faradays (2 x 96500 C). Calculate total charge needed and divide by time in seconds (5 hours = 18000 seconds) to find current.
