The equation Al2O3 + 2NH4Cl -> 2(NH4)2AlO2 + 2HCl

Detailed information about the reaction Al₂O₃ + 2NH₄Cl -> 2(NH₄)₂AlO₂ + 2HCl
This equation represents the chemical reaction process between aluminum oxide (Al₂O₃) and ammonium chloride (NH₄Cl) to produce ammonium aluminate ((NH₄)₂AlO₂) and hydrochloric acid (HCl). The number of moles of each involved substance is represented by the coefficients in the equation.

Reaction conditions
The chemical reaction between Al₂O₃ and NH₄Cl usually occurs at high temperatures and normal pressure.

Reaction process
The reaction begins by dissolving Al₂O₃ in an NH₄Cl solution, then the temperature is raised to stimulate the chemical reaction. The result is the formation of (NH₄)₂AlO₂ and HCl.

Occurring phenomena
During the reaction process, changes in color, temperature, and pressure can be observed, due to the release of heat and the formation of new products. Specifically, (NH₄)₂AlO₂ usually appears as a white solid, while HCl is a gas with a distinctive smell.
