Industrial Applications of Chemistry: Experiment on Electroplating
Objective:

To demonstrate the process of electroplating and observe its applications in industry.


Materials:

  • 9-volt battery
  • Copper wire (2 pieces, 1 m each)
  • Copper sulfate solution (10%)
  • Steel nail
  • Voltmeter
  • Ammeter
  • Crocodile clips

Procedure:

  1. Set up the electrochemical cell by connecting the 9-volt battery to the copper wires using crocodile clips.
  2. Immerse the steel nail and one piece of copper wire (the electrode to be plated) into the copper sulfate solution, ensuring they do not touch each other.
  3. Connect the positive terminal of the battery to the steel nail (the anode) and the negative terminal to the copper wire (the cathode).
  4. Connect the voltmeter between the anode and cathode to measure the voltage.
  5. Connect the ammeter in series with the circuit to measure the current.
  6. Allow the electroplating process to continue for 15-20 minutes, observing the changes in the steel nail.
  7. Disconnect the power source and remove the steel nail from the solution.

Key Procedures:

  • Ensuring proper electrical connections for the flow of electricity.
  • Monitoring the voltage and current using the voltmeter and ammeter.
  • Allowing sufficient time for the electroplating process to create a noticeable layer of copper on the steel nail.

Significance:

This experiment illustrates the industrial application of electroplating in various fields such as:
