Question

How does AlCl₃ reacts with following reagents?

1. H₂O 

2. NH₄OH 

3. NaOH

Answer 1

1. When aluminium chloride reacts with water to form aluminium hydroxide.

AlCl₃ + 3H₂O → Al(OH)₃ + 3HCl 

2. With ammonium hydroxide, aluminium chloride forms aluminium hydroxide. 

AlCl₃ + 3NH₇OH → Al(OH)₃ + 3NH₄Cl 

3. With excess of sodium hydroxide AlCl₃ produces sodium meta aluminate.

AlCl₃ + 4NaOH → NaAlO₂ + 2H₂O + 3NaCl
