The equation 2K + 2H2O -> 2KOH + H2

  1. Detailed information about the equation 2K + 2H2O -> 2KOH + H2
    The above chemical equation describes the chemical reaction between potassium (K) and water (H2O) to form potassium hydroxide (KOH) and hydrogen gas (H2).

  2. Reaction conditions
    For the reaction to occur, potassium needs to be placed in a water environment and requires an appropriate temperature. Potassium is an alkali metal, so it can react strongly with water.

  3. Reaction process
    During the reaction process, each potassium molecule will react with one water molecule, forming one potassium hydroxide molecule and releasing one hydrogen gas molecule.

  4. Phenomenon occurred
    When potassium reacts with water, gas bubbles will appear. This is the hydrogen gas created during the reaction. In addition, if you observe carefully, you will also see a layer of solid substance adhering to the water surface after the reaction, which is potassium hydroxide.
