FWS – The Briggs-Rauscher Reaction

April 28, 2016 // 0 Comments

The Briggs-Rauscher reaction is a colourless solution that becomes amber then suddenly turns blue-black. The blue-black will fade to colourless, and the cycle will repeat several times with a period which initially lasts a few seconds but gradually lengthens. After a few minutes the solution will remain blue-black that liberates iodine vapors. The reaction can occur via two differ processes. A radical process and a non radical process. Which of these two processes dominates is determined by [...]

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 – The Iodine Clock Reaction

January 8, 2016 // 0 Comments

  The iodide clock reaction is one of the classic chemical reactions you are shown in school/university. Two colourless solutions are mixed together and, in a given amount of time, the solution suddenly turns dark blue – almost black. There are several variations of the clock reaction but this video concentrates on the iodate version. The chemistry is rather difficult as there are multiple reactions going on. The first is in one of the clear solutions where bisulfate is generated [...]

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- → [...]

FWS – Ant Colony Vlog #3

Its been a very eventful month for the ants in the gel ant farm. The queen ant has started to started to lay eggs and Myles was lucky enough to catch her doing this on camera. “How it Begins” Kevin MacLeod (incompetech.com) Licensed under Creative Commons: By Attribution 3.0 http://creativecommons.org/licenses/by/3.0/ Intro Music by Michael ‘Skitch’ Schiciano bio: http://bio.skitchmusic.com soundcloud: http://www.soundcloud.com/skitchstudio [...]
