Question

Choose the correct words or phrases from the brackets to complete the following sentences:

Heating ammonium chloride with sodium hydroxide produces _____. (ammonia/nitrogen)

Answer 1

• When solid ammonium chloride $\left({\mathrm{NH}}_4\mathrm{Cl}\right)$ is heated in the presence of sodium hydroxide $\left(\mathrm{NaOH}\right)$ solution, ammonia gas $\left({\mathrm{NH}}_3\right)$ is produced, which has a strong pungent odor.
• The reaction is as follows:
  ${\mathrm{NH}}_4\mathrm{Cl}\left(\mathrm{s}\right)+\mathrm{NaOH}\left(\mathrm{aq}\right)\to \mathrm{NaCl}\left(\mathrm{aq}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)+{\mathrm{NH}}_3\left(\mathrm{g}\right)\uparrow$
• Thus, Heating ammonium chloride with sodium hydroxide produces ammonia.
