Question

Write the equation for the following reaction: Aluminium nitride and water.

Answer 1

Laboratory Preparation of Ammonia$\left({\mathrm{NH}}_3\right)$ from aluminum Nitride$\left(\mathrm{AlN}\right)$:

• In the laboratory, ammonia gas can also be prepared by pouring warm water on aluminum nitride.
• When water is poured over aluminum nitride, ammonia gas and hydroxide of aluminum is formed.

Therefore, equation for the reaction of aluminum nitride and water is:

$\mathrm{AlN}\left(\mathrm{s}\right)+3{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)⟶\mathrm{Al}(\mathrm{OH}{)}_3\left(\mathrm{aq}\right)+{\mathrm{NH}}_3(\mathrm{g})\uparrow$
