Solve problems and analyse information to calculate the potential (E°) requirement of named electrochemical processes using tables of standard potentials and half-equations

Table of standard potentials: A table that lists common reduction half-equations along with the potentials of the half-equations, known as reduction potentials, relative to the standard hydrogen electrode.

Oxidation potentials (potentials of the reverse half-equations to those listed) are equal in magnitude but opposite in sign to reduction potentials.

The overall potential of an electrochemical process can be calculated by adding the reduction potential to the oxidation potential:

If the potential is positive, then the reaction is spontaneous (i.e. it is a galvanic cell).

If the potential is negative, then the reaction requires the application of a voltage greater than or equal to the magnitude of the potential (i.e. it is an electrolytic cell).
