Question

Why does the aqueous solution of an acid conduct electricity?

Hint:

Acids in aqueous solution conduct electricity due to the presence of free-moving ions.

Answer 1

Acids ionize in water to release H\(^+\) (hydrogen) ions, which are responsible for electrical conductivity. Example: \[ HCl \rightarrow H^+ + Cl^- \] Since free-moving ions (\( H^+ \), \( Cl^- \)) are present in solution, they allow the conduction of electricity.
