Standard Electrode Potentials
AQA A-Level Chemistry
3.1.11
This topic explains how standard electrode potentials are measured using the standard hydrogen electrode and what E° values tell us about oxidation, reduction, and electron flow in electrochemical cells. It is important for understanding electrode potential data, predicting reactions, and calculating cell EMF in AQA exams.
Begin with the Learn section if this is your first time covering the topic. If you are revising, move to Revise. If you are testing yourself, go straight to Practise.
In this topic you will:
- Understand what electrode potential represents in a half-cell.
- Learn how the standard hydrogen electrode is used to measure standard electrode potentials.
- Understand the importance of standard conditions in electrochemistry.
- Understand how standard electrode potentials relate to cell EMF calculations.
