In an electrochemical cell the cathode is the
In chemistry, a cathode is the electrode of an electrochemical cell at which reduction occurs. The cathode can be negative like when the cell is electrolytic (where electrical energy provided to the cell is being used for decomposing chemical compounds); or positive as when the cell is galvanic (where chemical reactions are used for generating electrical energy). The cathode supplies electrons to the positively charged cations which flow to it from the electrolyte (even if the cell i… WebEach half of the electrochemical cell has an electrode to which the wire for our external circuit is connected. The chemistry takes place at the surface of this electrode. The electrode on the oxidation side is called the anode. The electrode on the reduction side is called the cathode.
