Reaction when potassium reacts with water
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 ). WebThe reaction of a group 1 metal with a group 7 element is also a redox reaction. For example, the reaction of potassium with iodine to form potassium iodide: 2K(s) + I 2 (s) → 2KI(s)
