FWS – Trying to Destroy My Wii with Potassium Permanganate & Glycerol

April 6, 2016 // 0 Comments

So believe it or not I had another games console break on me. This time it was my Nintendo Wii and, like before, I had to take out my aggression on it using some SCIENCE or, more specifically, potassium permanganate and glycerol. Potassium permanganate is a strong oxidiser and when in contact with glycerol, bursts into flames. 14KMnO4 + 4C3H5(OH)3 —-> 7K2CO3 + 7Mn2O3 +5CO2 [...]

FWS – Chemical Chameleon Reaction

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- → [...]
