Solution

The metal that gets coated during electroplating is D. The metal that is the cathode.

Here's the step by step process:

  1. In electroplating, the object to be plated (coated with a different metal) is made the cathode (negative electrode) of an electrolysis cell.

  2. The metal to be plated onto the object is made the anode (positive electrode).

  3. When electricity is passed through the cell, metal ions from the anode metal are oxidized (lose electrons) to form cations that go into solution in the electrolyte.

  4. These metal cations are then reduced (gain electrons) at the cathode, plating the cathode with a layer of metal.
