IB Chemistry Topic 9.2: Electrochemical cells

The video starts on the Winkler method, and how to calculate biochemical oxygen demand using this, with an example question. It then delves into voltaic cell structure, include anode and cathode reactions, cell notation with example questions, and how to quantify reactions. The video finishes on electrolytic cells and the reactions that occur during molten electrolysis.
