The correct Answer is:
To electroplate an iron object with a layer of nickel, follow these steps: ### Step-by-Step Solution: 1. **Prepare the Electrolyte Solution**: - You need to prepare a nickel sulfate solution. This solution will provide the nickel ions necessary for the electroplating process. 2. **Set Up the Electroplating Apparatus**: - Take two electrodes: an anode and a cathode. The anode will be made of nickel, while the cathode will be the iron object you want to electroplate. 3. **Connect the Electrodes**: - Connect the anode (nickel electrode) to the positive terminal of the battery. - Connect the cathode (iron object) to the negative terminal of the battery. 4. **Submerge the Electrodes**: - Place both the anode and cathode into the nickel sulfate solution. Ensure that they do not touch each other. 5. **Turn On the Power Supply**: - Switch on the battery. This will start the electroplating process. 6. **Electroplating Process**: - Nickel ions from the solution will migrate towards the cathode (iron object) and deposit onto its surface, forming a layer of nickel. 7. **Monitor the Process**: - Keep an eye on the electroplating process. The duration will depend on how thick you want the nickel layer to be. 8. **Completion**: - Once the desired thickness of the nickel layer is achieved, turn off the power supply and remove the iron object from the solution.
