Electrode potentials & Cells

AQA Content

Use EƟ values to predict the direction of simple redox reactions
Calculate the EMF of a cell
Write and apply the conventional representation of a cell.

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.
