This experiment allows for a study of the electrolysis of water without the use of the traditional Hoffman apparatus. An experimental study of the electrolysis of water can be used to demonstrate oxidation-reduction reactions or to illustrate the use of an external source of energy to drive a non-spontaneous chemical reaction.
The relative volumes of the gases produced and the reactions of the gases to the glowing and burning splints can be compared with the theory of the production of oxygen at the anode and hydrogen at the cathode. The colors produced at each electrode can be used to identify the production of hydrogen ion at the anode and hydroxide ion at the cathode.
