What an electrochemical cell does

What an electrochemical cell does

Labelled zinc-copper electrochemical cell showing zinc anode, copper cathode, electron flow through the wire, and ion movement in the salt bridge An electrochemical cell uses a spontaneous redox reaction to push electrons through an external wire. Splitting the reaction into two half-cells turns chemical change into a measurable voltage.

Step-by-step lessons on Edexcel A Level Chemistry Electrochemical cells. Each one builds up to exam-style questions. Build confidence with atomic structure, bonding and moles calculations early on, since these underpin the more demanding organic mechanisms, equilibrium and practical-analysis topics that dominate Year 2.
