Aqueous copper (II) sulphate was electrolysed using the set up below.
- When the switch was closed a gas was produced only at electrode B. Which electrode is the anode?
- Write the half equation for the reaction occurring at electrode B.
- What happens to the PH of the electrolyte during electrolysis? Explain.
- If carbon electrodes were replaced with copper electrodes in the cell above, write the equation of the reaction that would occur at the anode.
