Potassium Permanganate Colour Change

Potassium Permanganate Colour Change - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=OLUyeCC-2KoNOTE FROM THE PROFESSOR: The colour change is caused by the purple permanaganate ions [MnO4]- gaining electrons to form colourless Mn(+2) ions. The oxygen from the permanganate and the H2O2 are converted to H2O and O2 (which bubbles off). The extra H atoms come from the sulphuric acid H2SO4. Both the K and Mn end up as sulfates.See our 24 reactions playlist as it unfolds at: http://www.youtube.com/playlist?list=PL6E4F35510525FFF7Berzelius Day explained: http://www.youtube.com/watch?v=wDXUDq2KLM4More chemistry at http://www.periodicvideos.com/Follow us on Facebook at http://www.facebook.com/periodicvideosAnd on Twitter at http://twitter.com/periodicvideosFrom the School of Chemistry at The University of Nottingham: http://www.nottingham.ac.uk/chemistry/index.aspxPeriodic Videos films are by video journalist Brady Haranhttp://www.bradyharan.com/
