WebGeneral. All of these metals react vigorously or even explosively with cold water. In each case, a solution of the metal hydroxide is produced together with hydrogen gas. 2X (s) + H 2 O (l) 2XOH (aq) + H 2 (g) This equation applies to any of these metals and water - just replace the X by the symbol you want. WebPotassium in water (K + H2O)
WebPotassium metal reacts very rapidly with water to form a colorless basic solution of potassium hydroxide (KOH) and hydrogen gas (H2). The reaction continues even when the solution becomes basic. The resulting solution is basic because of the dissolved hydroxide. The reaction is exothermic. Potassium is very soft and easily cut. WebJan 27, 2015 · Molecular dynamics analysis indicated that nearly instantaneous transfer of electrons from the spikes to the water rapidly generates positively charged alkali ions, which vigorously repel and …
