In electrolysis, a nonspontaneous redox reaction is forced to occur by applying an electric current. This is done to separate a compound into its constituent elements or to deposit a material onto a surface. Pure, drinkable water is not always produced and electrolysis does not involve a cell that reverses the flow of ions.
