The chemical equation Al2O3 + 2NH4SO4 -> 2(NH4)3AlO3 + 2SO2 + 3H2O

  1. Detailed information about the equation Al2O3 + 2NH4SO4 -> 2(NH4)3AlO3 + 2SO2 + 3H2O:

    • The compounds on the left side of the equation are Al2O3 (aluminum oxide) and NH4SO4 (ammonium sulfate).
    • The compounds on the right side of the equation are (NH4)3AlO3 (aluminium ammonium sulfate), SO2 (sulfur dioxide or sulfur (IV) oxide) and H2O (water).
    • The molar quantities of these substances balance each other according to the given molar ratio.

  2. Reaction conditions:
    This reaction usually occurs at high temperatures.

  3. Reaction process:

    • Firstly, NH4SO4 reacts with Al2O3 to create (NH4)3AlO3.
    • Then, (NH4)3AlO3 continues to react with SO2 to produce the final products, which are SO2 and H2O.

  4. Observable phenomena:
    During the reaction, one can observe a bubbling phenomenon due to the formation of SO2 and H2O gases.
