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). -
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. -
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. -
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.
