potassium metal reacts with water to give potassium hydroxide and hydrogen gas?

Question: Potassium metal reacts with water to give potassium hydroxide and hydrogen gas?

Yes, that is correct. When potassium metal reacts with water, it undergoes a vigorous exothermic reaction, producing potassium hydroxide (KOH) and hydrogen gas (H2) as products. The balanced chemical equation for the reaction is:

2K(s) + 2H2O(l) → 2KOH(aq) + H2(g)

This reaction is highly exothermic and can result in the ignition of the hydrogen gas produced. Therefore, it is important to handle potassium metal with care and to carry out the reaction under controlled conditions. Potassium metal is a strong reducing agent and reacts readily with many other substances, including air and moisture in the air, which is why it is usually stored under an inert gas such as argon to prevent it from reacting.
