November 18, 2015 // 0 Comments

The chemical chameleon reaction is a two step reaction in which you can visualise various oxidation states of manganese starting with potassium permanganate (+7) and ending with manganese dioxide (+4). The reaction is performed in alkaline conditions using caster sugar as a reduction agent. In the first step of this reaction, the purple potassium permanganate is being reduced down to the green manganate ion. A mixture of these two compounds gives the solution a blue colour. MnO4- + e- → [...]
