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.
