The equation Al + 3NaOH -> 2NaAlO2 + 3H2

  1. Detailed information about the chemical equation:
  • General equation: Al + 3NaOH -> 2NaAlO2 + 3H2
  • Where, Al is aluminium metal, NaOH is sodium hydroxide, NaAlO2 is sodium aluminate, H2 is hydrogen gas.
  1. Reaction conditions
  • The reaction occurs at high temperatures.
  • A sufficient amount of NaOH is needed to react with Al.
  1. Reaction process
  • Aluminium metal (Al) reacts with sodium hydroxide solution (NaOH) to form sodium aluminate (NaAlO2) and hydrogen gas (H2).
  1. Phenomena occur
  • When Al reacts with NaOH, if the reaction occurs under sufficient heat conditions, hydrogen gas bubbles will continue to be emitted, and the amount of solid in the solution decreases. This is a sign indicating that the chemical reaction has taken place.
