<P> Electrolysis of water is the decomposition of water into oxygen and hydrogen gas due to an electric current being passed through the water . The reaction has a standard potential of − 1.23 V, meaning it ideally requires a potential difference of 1.23 volts to split water . </P> <P> This technique can be used to make hydrogen fuel (hydrogen gas) and breathable oxygen; though currently most industrial methods make hydrogen fuel from natural gas instead . </P>
