Question
Describe the procedure for investigating the electrolysis of an aqueous solution using inert electrodes.
Answer
To investigate electrolysis of an aqueous solution using inert electrodes, set up a beaker containing the solution and insert two inert electrodes, such as graphite rods. Connect the electrodes to a power supply, ensuring the positive electrode is connected to the anode and the negative to the cathode. Turn on the power supply and observe the products formed at each electrode, noting any gas evolution or color changes.
Explanation
This answer demonstrates understanding of the experimental setup and the role of inert electrodes in electrolysis. It tests the ability to describe a practical investigation, which is key in chemistry education.
Common mistake
Inert Electrode Confusion
Students often confuse inert electrodes with reactive electrodes, thinking that inert electrodes participate in the reactions.
Remember that inert electrodes, such as graphite or platinum, do not react during electrolysis; they only provide a surface for the reactions to occur.
