Question

Why does an aqueous solution of an acid conduct electricity?

Answer 1

Conduction of the electricity:

• For the conduction of electricity, there is a need for Charge carriers like ions or free electrons.
• These charge carriers conduct electricity.

Acidic Aqueous Solution:

• In an aqueous solution, acids dissociate to produce ${\mathrm{H}}^{+}$ ions.
• These ions are responsible for the conduction of electricity.
• The following dissociation takes place:
• $$\begin{gathered} \mathrm{HCl}\left(\mathrm{aq}\right)\to {\mathrm{H}}^{+}\left(\mathrm{aq}\right)+{\mathrm{Cl}}^{–}\left(\mathrm{aq}\right) \\ \mathrm{Hydrochloric}\mathrm{Hydrogen}\mathrm{Chlorine} \\ \mathrm{Acid}\mathrm{Ion}\mathrm{Ion} \end{gathered}$$
