Question

Ammonia does not conduct electricity but ammonium hydroxide conducts electricity.give reason

Answer 1

Electricity conduction depends upon presence of ions. Ammonia gas does not contain ions to conduct electricity while aqueous solution of ammonia i.e. ammonium hydroxide conducts electricity because in solution stage it has ions to move. NH3 (aq) + H2O ⇔ NH4 + + OH-.
