Purification of chromium can be achieved by electrorefining chromium from an impure chromium anode onto a pure chromium
cathode in an electrolytic cell. How many hours will it take to plate 15.5 kg of chromium onto the cathode if the current passed
through the cell is held constant at 42.0 A? Assume the chromium in the electrolytic solution is present as Cr³+.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F300bb3fc-30fb-4ed8-915b-7714493d9dc6%2F6f1a571e-19a7-4def-8847-89e8e88419ac%2Ffugs0wk_processed.jpeg&w=3840&q=75)
