How It Is Used
Clamp the apparatus upright on a stand, fill it with water containing sodium or potassium sulphate or sulphuric acid, and connect the terminals to a 12V DC source. The gas in each limb is measured on the graduations and then tested with a match. It shows the decomposition of water, chemical composition by electrolysis and the electrochemical equivalent of hydrogen.
