Question

Suppose a budget jewelry maker was looking to plate a nickel ring base with an outer gold layer. Describe how he might be able to do this using electroplating techniques. What would serve as the anode, the cathode, the electrolyte, etc.

Answer 1

The overall process the jewellery maker might be follow is described in the attached image.

alled The electroplating technique the budget jewelry a maker should be using here is electro deposition. He was looking to plate a nickel dring base with an senuten gold layer. So the nickel oring would the cathod and the gold would serove as the anode here in this circuit. The both the cathod components, ie, the and the anode I would immersed , be immerse in a solution called an electrolyte which would be made of or containing one or more dissolved gold salts as well as other lons that permit the flow of dectricity. A power supply which was connected in the circuit supplied the electricity (direct current) to the anode oxidising the gole atoms and ò the gold ions de were dissolved in the solution. At the cathod, the dissolved gold ions in the electrolyte solution were reduced at the surface, between the solution and the cathod and at last they plated out in the cathod and the gold plated on the nickel ring,
