The equation 2Li + 2HCl -> 2LiCl + H2

  1. Detailed information about the equation 2Li + 2HCl -> 2LiCl + H2:

    • On the left-hand side of the equation, we have two atoms of Lithium (Li) and two molecules of hydrochloric acid (HCl).
    • On the right-hand side of the equation, we have two molecules of lithium chloride (LiCl) and one molecule of hydrogen (H2).
    • The number of atoms of each element on both sides of the equation are equal, indicating that the equation has been balanced.

  2. Reaction conditions:

    • This reaction requires the presence of a catalyst.
    • The reaction temperature is not specified, but the reaction usually takes place at room temperature.

  3. Reaction process:

    • In this process, hydrochloric acid (HCl) reacts with lithium (Li) to form lithium chloride (LiCl) and hydrogen (H2).
    • This is a substitution reaction in which lithium replaces hydrogen in hydrochloric acid to form lithium chloride, while hydrogen escapes in the form of hydrogen gas.

  4. Phenomena that occur:

    • During the reaction, one can observe the boiling of the solution due to the escape of hydrogen gas.
    • A change in the color of the solution from the transparent color of hydrochloric acid to the white color of the lithium chloride solution can also be observed.
