Learning Paths
Each learning path is one chapter: a guided route through a topic, one small course at a time. Pick a class to see its chapters in order.
Chapter 22Contains Standard content
Conductance, Electrolysis and Batteries, Galvanic Cells, Electrode Potential and the Nernst Equation
A phone battery, a rusting bridge and the silver plating on a spoon all depend on electrons moving through a circuit while a reaction runs. In this chapter you learn how a cell's emf is linked to Gibbs energy and to the Nernst equation, how electrolytes conduct, and what Faraday's laws say about electrolysis. You also meet batteries, fuel cells and corrosion. Python computes cell potentials and the charge needed to deposit a metal.
