Question

Write balanced equation for the following reaction:

(a) Solutions of ammonium chloride and sodium hydroxide are mixed.

Answer 1

Reaction summary:

• When Ammonium chloride $\left({\mathrm{NH}}_4\mathrm{Cl}\right)$ reacts with sodium hydroxide$\left(\mathrm{NaOH}\right)$, then Ammonia gas $\left({\mathrm{NH}}_3\right)$ is liberated along with the formation of sodium chloride $\left(\mathrm{NaCl}\right)$ and water$\left({\mathrm{H}}_2\mathrm{O}\right)$.

Skeleton reaction:

${\mathrm{NH}}_4\mathrm{Cl}\left(\mathrm{aq}\right)+\mathrm{NaOH}\left(\mathrm{aq}\right)\to {\mathrm{NH}}_3\uparrow +{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)+\mathrm{NaCl}\left(\mathrm{aq}\right)$

• In this reaction, all the atoms in the respective reactant and product sides have the same numbers. Thus, this is a balanced chemical reaction.

Balanced chemical reaction:

${\mathrm{NH}}_4\mathrm{Cl}\left(\mathrm{aq}\right)+\mathrm{NaOH}\left(\mathrm{aq}\right)\to {\mathrm{NH}}_3\uparrow +{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)+\mathrm{NaCl}\left(\mathrm{aq}\right)$
