Key Concepts

Electrochemical Cell Notation

This is the shorthand representation of the cell, where the anode (site of oxidation) is written on the left and the cathode (site of reduction) on the right. The vertical lines separate the different phases or interfaces, and a double vertical line denotes the salt bridge or junction between the half-cells. This notation helps in identifying which electrode undergoes oxidation and which undergoes reduction based on the order of potentials provided.

Spontaneous Reaction

A positive overall cell potential indicates that the redox reaction is spontaneous within a galvanic (voltaic) cell. The direction of electron flow—from the anode where oxidation occurs to the cathode where reduction happens—reflects the natural drive of the system to reach a lower energy state.

Half?Cell Reactions

Electrochemical cells consist of two half?cells, each involving a redox reaction. One half-reaction occurs by reduction (gain of electrons) at the cathode, while the other, which is the reverse of a reduction (oxidation or loss of electrons), occurs at the anode. The standard electrode potentials are given for the reduction processes, and if a reaction is reversed to represent oxidation, the sign of its standard potential is also reversed.

Cell Potential Calculation

The overall cell potential (electromotive force, EMF) is calculated by taking the difference between the cathode and anode standard potentials (E°cell = E°cathode ? E°anode). When the half-reaction at the anode is reversed from its standard reduction form, its effective potential becomes negative. This difference indicates the driving force of electron flow in the cell.

Standard Electrode Potential

The standard electrode potential is the inherent tendency of a chemical species to be reduced under standard conditions. It is measured in volts relative to the standard hydrogen electrode (SHE). These potentials allow for the prediction of which half?reactions will proceed as reductions and which as oxidations when two electrodes are paired.
