My son is performing a science fair experiment using the classic electrolysis of water with a 6 volt battery producing hydrogen at one electrode and oxygen at the other. He is capturing the two gases in an inverted test tube. We have encountered a major problem. Hydrogen is readily being produced at one electrode, however no oxygen is being produced at the other. We are using two copper wires for the electrode which is placed in a beaker of tap water with a tablespoon of salt as the electrolyte. Can someone offer an explanation as to why there are no bubbles or the appearance of oxygen at the one electrode.
