When Lithium reacts with water: Reaction: 2Li (lithium) 2H₂O (water) → 2LiOH (lithium hydroxide) H₂ (hydrogen gas) Observations: - Lithium reacts steadily with water, releasing hydrogen gas - The reaction is exothermic, producing heat - Lithium hydroxide is formed, increasing the pH of the solution Characteristics: - Less reactive than sodium and potassium, but still requires caution - Reactivity increases with temperature and surface area Safety Precautions: - Handle lithium with care, wearing
