Electrolysis Science Experiment Elec­trol­y­sis is an ox­i­da­tion-re­duc­tion process which takes place on elec­trodes when a di­rect cur­rent pass­es through an al­loy or so­lu­tion of elec­trolyte. An elec­trol­yser is a con­tain­er in which elec­trol­y­sis takes place. It con­sists of two elec­trodes - pos­i­tive (an­ode) and neg­a­tive (cath­ode). l.
