What Causes Potassium to Explode in Water?
Chemists have long believed that throwing a lump of alkali metal into water, a time-honored technique still conducted by some lecturers and many chemical thrill seekers, generates an explosion because the metal dissolves, releasing high heat and transferring electrons to the water. The dissolving step also produces steam and makes hydroxide ions and hydrogen, which can be burnt to increase the process's energy.
They understood that the steam and hydrogen produced early in the reaction should form a buffer layer over the metal surface, preventing water from reacting further.
