An electrode of an electrically conducting polypyrrole polymer is used in the electrolysis process for the production of chlorine gas from aqueous chloride solutions. The chloride anion is readily oxidized in an aqueous solution containing 0.2M NaCl and 0.01M HCl to form chlorine gas which is detected visually. A polypyrrole polymer electrode is more resistant to corrosion than a conventional electrode made of carbon or platinum.
