ELECTROCHEMISTRY NUMERICALS PDF

Main article: Electrochemical cell An electrochemical cell is a device that produces an electric current from energy released by a spontaneous redox reaction, this can be caused from electricity. This kind of cell includes the Galvanic cell or Voltaic cell, named after Luigi Galvani and Alessandro Volta , both scientists who conducted several experiments on chemical reactions and electric current during the late 18th century. Electrochemical cells have two conductive electrodes the anode and the cathode. The anode is defined as the electrode where oxidation occurs and the cathode is the electrode where the reduction takes place.
