Electroplating is a widely used process. One of the most popular electroplating processes involves the plating of two metals, nickel and chromium, in separate vats. Nickel is plated first because it adheres better to iron, then the object is moved to a second vat where a layer of chromium is plated. The half-reactions occurring in each vat are shown below:

Plating of Nickel        Ni2+(aq) + 2 e- → Ni(s)

Plating of Chromium   Cr2O72-(aq) + 14 H+(aq) + 12 e- → 2 Cr(s) + 7 H2O(l)

Describe a strategy that can be used in electroplating to maintain the concentration of aqueous ion in the vat where nickel is plated.
