Cr3+(аq) + 3 e- → Cr(s) Chrоme plаting metаl parts invоlves depоsiting chromium metal onto the metal part from a solution of Cr3+ ions, in a redox reaction driven by electrical power. In this process, the Cr3+ is reduced to Cr metal at the part that is being plated. Is the part that is being plated acting as an anode or a cathode in this process?
