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. This example explains why the process is called electrolysis.The suffix -lysis comes from the Greek stem meaning to loosen or split up.
