The electrolysis of sodium chloride solution using a mercury cathode This is a good example of a case where the nature of the electrode makes a huge difference. This was once a major industrial method for manufacturing sodium hydroxide solution as well as chlorine and hydrogen, but it has been largely replaced by more environmentally friendly. The potential required to oxidize Cl-ions to Cl 2 is -1.36 volts and the potential needed to reduce Na + ions to sodium metal is -2.71 volts. The battery used to drive this reaction must therefore have a potential of at least 4.07 volts.
