The equation Al + 3KOH -> 2KAlO2 + 3H2

  1. Detailed information about the equation Al + 3KOH -> 2KAlO2 + 3H2

  • This is the reaction equation between aluminum (Al) and alkali (KOH), producing potassium aluminate (KAlO2) and hydrogen (H2).

  • If analyzed by atomic balance, we can see that the left side of the equation has 1 Al atom, 3 K atoms, 3 O atoms and 3 H atoms. The right side of the equation has the corresponding number of atoms.

  1. Reaction conditions
  • This reaction usually occurs at room temperature or slightly higher to stimulate the reactant molecules.
  1. Reaction process
  • Aluminum reacts with a strong alkali (KOH) to produce potassium aluminate and hydrogen.
  1. Phenomena occurring
  • When pouring the KOH solution into aluminum, bubbles will form, indicating the production of hydrogen.
  • The color of the solution will change.
  • If the reaction is intense, heat may be generated enough to warm the solution.
