Here's the chemical reaction:
2K (s) + 2H₂O (l) → 2KOH (aq) + H₂ (g)
This reaction is a vigorous exothermic reaction where:
* Potassium (K) is a highly reactive alkali metal.
* Water (H₂O) acts as both a reactant and a solvent.
* Potassium hydroxide (KOH) is formed as a product, which is a strong base.
* Hydrogen gas (H₂) is also released as a byproduct.
Important Note: This reaction is highly dangerous due to the rapid release of heat and the flammability of hydrogen gas. It should only be performed by trained professionals in a controlled environment.
