Potassium in Water - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at: [ Ссылка ]
NOTE 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.
