Reaction when potassium reacts with water

WebPotassium reacts violently with water to produce half a mole of hydrogen per mole of potassium and water and generates approximately 47 kilocalories per mole of heat. Potassium can be stored in nitrogen gas with no reaction. It reacts with hydrogen at approximately 350 °C (660 °F) to form the hydride. WebJan 27, 2015 · For decades, science enthusiasts have delighted at the famously energetic way sodium and potassium explode on contact with water. Researchers in Europe now show that the long-accepted explanation for the way that process unfolds is incomplete (Nat. Chem. 2015, DOI: 10.1038/nchem.2161 ).
