The chemical equation Al2O3 + 2NH4SO4 -> 2(NH4)2AlO2 + 2SO2 + 3H2O.

1. Detailed information about the equation Al₂O₃ + 2NH₄SO₄ -> 2(NH₄)₂AlO₂ + 2SO₂ + 3H₂O

The above chemical equation describes the reaction process between aluminum oxide (Al₂O₃) and ammonium sulfate (NH₄SO₄), producing ammonium aluminate ((NH₄)₂AlO₂), sulfur dioxide (SO₂), and water (H₂O).

2. Reaction conditions

This reaction requires high temperatures to proceed.

3. Reaction process

This process begins by heating the aluminum oxide and ammonium sulfate. When the mixture reaches the optimal temperature, the compounds start to react with each other. This reaction produces ammonium aluminate, sulfur dioxide, and water.

4. Phenomena occurring

When the reaction occurs, a notable phenomenon is the generation of sulfur dioxide (SO₂) gas and steam (H₂O). Sulfur dioxide is a colorless gas, but it has a distinctive unpleasant odor. The steam produced also contributes to increasing the pressure within the system.
