Question

(a)Why do acids not show acidic behaviour in the absence of water?
(b)	Why does an aqueous solution of an acid conduct electricity?
Why does distilled water not conduct electricity whereas rain water does?

Accepted Answer

Mainly the acid behaviour of an acid is due to the presence of hydrogen ions when acids are dissolved in It does not show acidic character in the absence of water because the dissociation of hydrogen ions from an acid occurs in the presence of water only.
The aqueous solution of an acid conducts electricity due to the presence of charged particles. The charged particles are ions Hydrogen and hydronium ions. They carry electric currents thus acids conducts electricity
Distilled water does not conduct electricity because distilled water is the purest water which is free from all the ionic species. But rainwater is not the pure form thus it contains impurities and therefore conducts electricity.
