Description
Each cell consists of a 75 x 25mm glass cylinder with a 2 hole rubber stopper fitted with 2 carbon electrodes.
Electrical contact is made through the crocodile clips and a piece of insulating material between the electrodes prevents short circuiting.
The gases evolved are collected in two 75 x 10mm test tubes suspended over the electrodes by a piece of wood and rubber bands.
