WebThe electrode where oxidation takes place is called the anode, and the electrode where reduction takes place is called the cathode. A salt bridge is used to balance the charges in the two compartments. Eventually, the reaction reaches equilibrium and at equilibrium, the voltage is equal to zero, which means there's no more current. WebMar 1, 2024 · 16.2: Galvanic cells and Electrodes. It is physically impossible to measure the potential difference between a piece of metal and the solution in which it is immersed. We can, however, measure the difference between the potentials of two electrodes that dip into the same solution, or more usefully, are in two different solutions.
