Question

Write balanced equation for the following reaction:

A mixture of ammonium chloride and slaked line

Answer 1

When Ammonium chloride$\mathbf{\left(}{\mathbf{NH}}_{\mathbf{4}}\mathbf{Cl}\mathbf{\right)}$ is reacted with Calcium hydroxide$\mathbf{\left(}\mathbf{Ca}{\mathbf{\left(}\mathbf{OH}\mathbf{\right)}}_{\mathbf{2}}\mathbf{\right)}$ or slaked lime then the Ammonia gas $\left({\mathrm{NH}}_3\right)$

is evolved and Calcium chloride$\left({\mathrm{CaCl}}_2\right)$ and Water as a product is formed.

Reaction between Ammonium chloride and slaked lime is represented as:

$\underset{\mathrm{Ammonium}\mathrm{chloride}}{\underbrace{2{\mathrm{NH}}_4\mathrm{Cl}\left(\mathrm{aq}\right)}}+\underset{\mathrm{Calcium}\mathrm{hyydroxie}}{\underbrace{\mathrm{Ca}{\left(\mathrm{OH}\right)}_2\left(\mathrm{aq}\right)}}\stackrel{∆}{\to }\underset{\mathrm{Ammonia}}{\underbrace{2{\mathrm{NH}}_3\left(\mathrm{g}\right)}}+\underset{\mathrm{Calcium}\mathrm{chloride}}{\underbrace{{\mathrm{CaCl}}_2\left(\mathrm{aq}\right)}}+\underset{\mathrm{Water}}{\underbrace{2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}}$
