What is electroplating?

• The process of painting metals

• The process of melting metals together

• The process of coating one metal object with another using electricity

• The process of heating metals to high temperatures

Why might metals be electroplated?

• For aesthetics and protection

• To make them magnetic

• To make them non-conductive

What is the role of the electrolyte in electroplating?

• To conduct electricity

• To dissolve the metal

• To heat the metal

• To cool the metal

What is the positively charged electrode called?

In copper plating, what is used as the electrolyte solution?

• Zinc sulfate solution

• Copper sulfate solution

• Silver nitrate solution

• Gold chloride solution

What happens to copper ions at the cathode during copper plating?

• They remain unchanged

• They evaporate

• They lose electrons and dissolve into the solution

• They gain electrons and deposit onto the brass

What is the process called when metal atoms lose electrons at the anode?

• Plating

• Electrolysis

• Reduction
