You would like to produce a gold-plated coin by plating gold onto a penny 1.90 cm in diameter. How many days will it take to produce a layer of gold 0.730 mm thick (on both sides of the coin) from an Au³⁺ bath using a current of 0.0200 A? (density of gold = 19.3 g/cm³) For the purposes of this problem, you can ignore the edges of the coin.

Electrolysis

Electrolysis is defined as the process of breaking down ionic compounds into their constituent elements by passing a direct electric current through the compound in a fluid state. The cathode reduces cations, while the anode oxidizes anions. An electrolyte, electrodes, and some form of external power source are the main components required for conducting electrolysis. A partition, such as an ion-exchange membrane or a salt bridge, may also be used, but this is optional. These are primarily used to prevent the products from diffusing near the opposing electrode.
