Oxidation and Reduction

Oxidation and Reduction

1. Define oxidation and reduction in terms of oxygen loss / gain, and identify such reactions from given information

   • Oxidation is the gain of oxygen. The loss of oxygen is the reduction.

2. Define redox in terms of electron transfer, and identify such reactions from given information

   • Oxidation and reduction reactions always occur together in a redox reaction. Redox changes can often be observed as significant colour changes e.g. rusting / corrosion of iron.iron + copper(II) sulfate → iron(II) sulfate + copper
   • oxidation is the loss of electrons, reduction is gain of electrons

3. that's it
