Electrochemical Cells
AQA A-Level Chemistry
3.1.11
This topic explains how electrochemical cells produce electricity using redox reactions in half-cells. It underpins how batteries work and how chemists compare different metals using electrode potentials.
It is important for understanding cell potential, electrode potentials, and standard electrode potentials in AQA exams.
In this topic you will:
- Learn what an electrochemical cell is.
- Understand how oxidation and reduction drive electron flow in electrochemical cells.
- Understand the role of half-cells in generating a potential difference.
- Understand how metal reactivity affects electrode potential.
