Electrolysis Splitting Materials via Energy

What is electrolysis? Process of forcing current through a cell to produce a chemical change Results in negative cell potential Occurs within an Electrolytic Cell (a cell system that performs electrolysis) Used to separate materials (H 2 O, ions in solutions, mixtures) Used in Electroplating

Like a Voltaic Cell …. But NOT!

Differences between Voltaics and Electrolytics

Electrolytic Cell Diagram DEMO

Uses of Electrolysis Electroplating – depositing a thin metal layer on top of another metal to improve appearance or resistance to corrosion Electroplating
