What happens when you mix Potassium and Water?

POP! Potassium meets Water

Potassium has one lonely outer electron that it REALLY wants to give away. Water happily takes it, and that swap releases lots of heat very fast. The heat sets the hydrogen gas on fire with a lilac flame and a loud pop!

The result

What it makes
Potassium hydroxide + hydrogen gas
Equation
2K + 2H₂O → 2KOH + H₂
When it happens
At room temperature

Fun fact from Fizzy: Potassium reacts so fast that it skates across the water on a cushion of gas.

🥽 Never try this at home! Real potassium can explode and burn. Scientists handle it with goggles, gloves and tiny amounts.
