An industrial chemist is demonstrating the electrolysis of concentrated sodium chloride solution (brine) using inert graphite electrodes. The apparatus must be set up so that the gaseous products formed at both electrodes can be collected separately.
Draw a labelled diagram of the apparatus that can be used to carry out this electrolysis and collect the gases.
