Which hydroxide is formed when lithium reacts with water?

Explanation:
When lithium reacts with water, it forms lithium hydroxide and hydrogen gas. The metal donates electrons to water, creating OH− ions in solution and releasing H2. The balanced equation is 2 Li + 2 H2O → 2 LiOH + H2. So the hydroxide produced is lithium hydroxide. Other compounds like oxide, carbonate, or hydride aren’t formed in this reaction—they arise from reactions with oxygen, carbon dioxide, or hydrogen under different conditions.
