Specification Notes
IUPAC convention for writing half-equations for electrode reactions.
Cells are used to measure electrode potentials by reference to the standard hydrogen electrode.
The importance of the conditions when measuring the electrode potential, E (Nernst equation not required).
Standard electrode potential, EƟ, refers to conditions of 298 K, 100 kPa and 1.00 mol dm−3 solution of ions.
Standard electrode potentials can be listed as an electrochemical series.
