The equation 2Li + 2H2O -> 2LiOH + H2

  1. Detailed information about the equation 2Li + 2H2O -> 2LiOH + H2

    • The reactants involved are Lithium (Li) and Water (H2O).
    • The products are Lithium Hydroxide (LiOH) and Hydrogen gas (H2).
    • The reaction belongs to the category of combination reactions, in which Lithium reacts with water to produce Lithium Hydroxide and Hydrogen gas.

  2. Reaction conditions

    • The reaction takes place at room temperature and atmospheric pressure.
    • Lithium needs to be thinly sliced to increase the contact surface with water.

  3. Reaction process

    • When Lithium comes into contact with water, it reacts with water, forming Lithium Hydroxide and Hydrogen gas.
    • The reaction is fast and exothermic.
    • Hydrogen gas will rise above the water surface.

  4. Observed phenomena

    • When Lithium comes into contact with water, bubbles appear (Hydrogen gas), and the temperature of the solution increases due to the exothermic reaction.
    • The formed Lithium Hydroxide solution is white and has basic properties.
