Salt Bridge: A device that connects two half-cells of an electrochemical cell, allowing ions to flow and maintain charge neutrality.
Electrolyte: A substance that conducts electricity by the movement of ions, present in each half-cell of a galvanic cell.
Oxidation/Reduction: Oxidation refers to loss of electrons while reduction refers to gain of electrons; these reactions occur at anode and cathode respectively in a galvanic cell.
