ELECTROLYSIS and CELLS
Doc Brown's Chemistry KS4 science-chemistry GCSE/IGCSE/O level/AS Revision
ELECTROCHEMISTRY revision notes on electrolysis, cells, experimental methods, apparatus, batteries, fuel cells and industrial applications of electrolysis
This section starts with an introduction to electrolysis explaining which liquids conduct and why can some liquids conduct electricity and others cannot? - electrolytes, electrodes, what happens on electrode surfaces, the products of electrolysis. There are tables of electrode reactions, descriptions of experimental methods of electrolysis and a summary table of the electrolysis products from many common melts or aqueous solutions that undergo electrolysis when a d.c. electric current is passed through them. There is also a list of links to revision notes on the application of electrolysis to various industrial processes. Simple cells, batteries and fuel cells are also described. This page should also prove useful for coursework projects in electrolysis e.g. help with ideas, apparatus, experimental methods, products collection, electrode equations and calculations etc. These revision notes on electrolysis should prove useful for the new AQA chemistry, Edexcel chemistry & OCR chemistry GCSE (9–1, 9-5 & 5-1) science courses.
