In Progress Lesson 1, Topic 1 In Progress Oxidation reactions In an oxidation reaction, one organic compound is oxidised, usually by an inorganic reagent. This means that the organic compound can either lose hydrogen or gain oxygenUsually the oxygen atoms produced by an oxidising agent are shown using the symbol [O]Example: Oxidation of ethanol using a mixture of sulfuric acid and potassium dichromate (VI) [O] It is important to use [O] to indicate an oxidation agent rather than O2 as that would have indicated that molecular oxygen was used
