anode


anode
The electrodeIn an electrochemical cell, a surface on which oxidation or reduction occurs; an electrode conducts electric current into or out of a cell. in an electrochemical cellA system containing an oxidation-reduction reaction in which oxidation and reduction reactions are physically separated and the transferred electrons pass through an electrical circuit. Voltaic (galvanic) cells produce and electic current; electrolyic cells use electric current to force a reaction to occur. where oxidationThat part of a chemical reaction in which a reactant loses electrons; simultaneous reduction of a reactant must occur. occurs. The positively charged electrode in a vacuum tube.
