(a)[3]
The table gives some details about the electrolysis of three different electrolytes with graphite electrodes. Complete Table 8.1 by naming the products at each electrode.
(b)[2]
Give two reasons why graphite is a suitable substance for making electrodes.
(c)[1]
Aluminium is made by electrolysing aluminium oxide dissolved in molten cryolite. At the anode, oxide ions react to form oxygen molecules. Construct the ionic half-equation for the reaction occurring at this electrode.
