Describe how to investigate electrolysis of aqueous solutions using inert electrodes. (AT 3, AT 7)

To investigate electrolysis of aqueous solutions using inert electrodes, set up a simple circuit with a power supply, inert electrodes (like graphite or platinum), and an electrolyte solution. Immerse the electrodes in the solution and connect them to the power supply. When electricity is passed through, observe the formation of gas bubbles at the electrodes, indicating the discharge of ions. The inert electrodes do not react with the electrolyte, allowing for clear observation of the products formed, such as hydrogen at the cathode and oxygen at the anode, depending on the ions present in the solution.
