R3.2 (AHL) Electrochemical cells
This AHL section on electrochemical cells includes the standard hydrogen electrode leading to the standard electrode potentials of half-cells. These values are used to obtain the redox reaction that occurs when two half-cells are connected and the value of the voltage produced by the whole cell. This value can then be used to obtain the Gibbs energy value for the reaction. Electrolysis is extended to include...
