11. Electrolytes Used: CuSO4, PbSO4, MnSO4, NiSO4, CdSO4

Procedure:

1. Select the solution.
2. Choose the cathode.
3. Choose the anode.
4. Select the voltage.
5. Select the resistance.
6. Select the time.
7. Click on the start button.
8. Note the total weight of cathode.
9. Determine the mass of metal deposited.

Observations and Calculations:

Initial weight of the cathode = 10 g

Final weight of the cathode = ............... g

Amount of metal deposited (m) = ............... g

Voltage used = ............... V

Resistance used = ............... Ω

Current (I = V / R) = ............... A

Time taken for complete deposition (t) = ............... sec

Result:

The amount of metal deposited on the electrode = ............... g

Points to Remember while Performing the Experiment:

• Wear lab coat and gloves in the lab.
• Switch on the exhaust fan when entering the lab.
• Check if chemicals and reagents are available; prepare if not.
• Clean all apparatus with chromic acid and distilled water.
• Ensure apparatus are dry before use.
• Calibrate the weighing balance before measurements.
• Ensure voltmeter, ammeter, and rheostat work properly.
• Clean glassware with soap and distilled water.
• Recap reagent bottles after use.
• Switch off light, exhaust fan, and gas cylinder before leaving.
• Dispose of used gloves in a waste bin.
