  4. 4

    Use copper wire as a cathode and connect it to the negative terminal.

  5. 5

    Submerge both the metal object and copper wire in the solution.

  6. 6

    Turn on the power source.

  7. 7

    Observe the electroplating process over 30 minutes.

  8. 8

    Remove the object, rinse it with water, and dry.

  9. 9

    Record observations and measure the thickness of the copper layer.

  10. 10

    Repeat with different objects to compare results.

Frequently Asked Questions

What is electroplating?

Electroplating is a process that uses electrical current to reduce dissolved metal cations so that they form a thin coherent metal coating.

Can I use other metal solutions?

Yes, other metal salts can be used, but they may require different conditions.

Is the process safe?

With proper safety precautions, the process is safe, but always handle chemicals carefully.
