SUMMARY
The reaction between AL(NO3)3 and NH3 occurs in two distinct steps. Initially, ammonia acts as a base, forming insoluble aluminum hydroxide (Al(OH)3) with aluminum ions. Subsequently, excess ammonia dissolves this hydroxide, resulting in a complex compound that incorporates six ammonia molecules. This process highlights the dual role of ammonia in both precipitating and complexing aluminum ions.
