The potential required to oxidize Clions 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.
