Understanding Chemistry
| |

These pages are designed to be read in sequence. In order to understand the topic fully, you really ought to read them through in this order. At the bottom of each page you will find a link to the next one. Explains how electrode potentials of metal / metal ion systems arise, and how they are measured. Introduces the important conventions used. Shows how ranking electrode potentials in order leads to the electrochemical series, and the relationship between this and oxidation and reduction. Explains how the electrode potentials (redox potentials) of more complicated systems can be measured and related to the electrochemical series. Shows the relationship between combinations of half cells and simple redox reactions carried out in test tubes. **Using redox potentials to predict the feasibility of reactions . . .**Explains how to use values of redox potentials to predict whether particular redox reactions are feasible.
