Potassium in Water - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: http://www.youtube.com/watch?v=pPdevJTGAYYNOTE FROM THE PROFESSOR: Potassium always seems to react particularly violently; 2K + 2H2O → 2KOH + H2. It may just be that we use bigger lumps of it or perhaps the melting point is just right for the metal to begin melting when the reaction is already going strongly.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/
