Potassium Reacting with Water

2K + 2H2O → 2KOH + H2

अवलोकन

Potassium reacts even more violently with water than sodium, instantly producing potassium hydroxide and hydrogen gas. The hydrogen ignites immediately with a characteristic lilac/violet flame from potassium vapor. The reaction can cause small explosions due to its extreme vigor.
