(a)[3]
Complete Table 8.1 by giving the product names at each electrode.
(b)[2]
Electrolysing aqueous copper(II) sulfate gives different products when copper electrodes are used rather than graphite electrodes. Describe the observations seen during electrolysis with copper electrodes.
(c)[1]
Magnesium is made by the electrolysis of molten magnesium chloride. At the anode, chloride ions react to form chlorine molecules. Construct the ionic half-equation for this electrode reaction.
