What are the products when potassium reacts with water?

Explanation:
When alkali metals meet water, they form a metal hydroxide and hydrogen gas. For potassium, this gives potassium hydroxide (KOH) and H2, as shown by the balanced equation 2K + 2H2O → 2KOH + H2. Potassium hydroxide dissolves in water to make a strongly alkaline solution, while hydrogen gas bubbles off. The other options would require oxygen, carbon dioxide, or chlorine to be present, which isn’t the case in this reaction.
