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

(a)The acidic behaviour of acid is due to the presence of hydrogen ions formed in water. Acids do not show acidic character in the absence of water as the dissociation of hydrogen ions from an acid occurs in the presence of water only.

(b) The aqueous solution of an acid conducts electricity due to the presence of charged particles called ions, that carry electric currents thus acids conducts electricity.

(c) Distilled water does not conduct electricity because it is the pure water which is free from all the ionic species. As rainwater is not the pure form, thus it contains impurities and therefore conducts electricity.
