We rely on electrochemical reactions all the time. For example, the energy we get out of the batteries that we use every day is supplied by chemical reactions. In this video we take a look on how electrochemical reactions work, and how these principles can be used to protect the metal parts of boats.

This is the fourth film in a series of seven videos produced by Molecular Frontiers and Eoscene Productions, in collaboration with Chalmers University of Technology in Gothenburg, Sweden, with financial support by Hasselbladsstiftelsen. We encourage you to use it in education, for example as an introduction to the corresponding chapter in the chemistry textbook!
