Galvanic Cell Terms

Define the terms anode, cathode, electrode and electrolyte to describe galvanic cells

  • Electrode: A conductor, which allows electrons to pass from the external circuit to a half-cell or vice versa.
  • Anode: The negative electrode, at which oxidation occurs.
  • Cathode: The positive electrode, at which reduction occurs.
  • Electrolyte: An aqueous or molten substance that conducts electricity.
  • All solutions in a galvanic cell are electrolytes, including the solutions in which the electrodes are immersed and the solution that forms the salt bridge.
