d) Metallic sodium is not produced by the electrolysis of sodium chloride. What change would you need to make to the electrolyte to obtain metallic sodium. e) Oxygen is formed at the positively charged anode when copper sulphate is electrolysed using inert electrodes. Explain how oxygen is formed from ions in the solution. Answers: 3. Thin layers of transition metals can be used to form a coating on objects made of a different transition metal. This can be done to protect them against corrosion and improve their appearance.
