Question

What is the difference between the chemical nature of an aqueous solution of hydrochloric acid and an aqueous solution of ammonia?

Answer 1

The differences between an aqueous solution of hydrochloric acid and an aqueous solution of ammonia:

An aqueous solution of Hydrochloric acid $\left(\mathrm{HCl}\right)$	An aqueous solution of Ammonia $\left({\mathrm{NH}}_3\right)$
An aqueous solution of Hydrochloric acid contains $\left({\mathrm{H}}^{+}\right)$ and $\left({\mathrm{Cl}}^{-}\right)$ ions. The chemical reaction is represented as: $\mathrm{HCl}\left(\mathrm{aq}\right)\rightleftharpoons {\mathrm{H}}^{+}\left(\mathrm{aq}\right)+{\mathrm{Cl}}^{-}\left(\mathrm{aq}\right)$	An aqueous solution of ammonia is formed by adding water to Ammonia. The chemical reaction is represented as: ${\mathrm{NH}}_3\left(\mathrm{g}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)\rightleftharpoons {{\mathrm{NH}}_4}^{+}\left(\mathrm{aq}\right)+{\mathrm{OH}}^{-}\left(\mathrm{aq}\right)$
Large amount of Hydrogen ion $\left({\mathrm{H}}^{+}\right)$	Large amount of Hydroxide ion $\left({\mathrm{OH}}^{-}\right)$
Turns blue litmus red.	Turns red litmus blue.
Acidic in nature.	Basic in nature…
