Presentation Transcript

  1. Electrolysis Splitting Materials via Energy

  2. 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 (H2O, ions in solutions, mixtures) • Used in Electroplating

  3. Like a Voltaic Cell …. But NOT!

  4. Differences between Voltaics and Electrolytics

  5. Electrolytic Cell Diagram DEMO

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

  7. Sample Exercise 20.14 p.861
