Give reasons:NH3 gas a covalent compound does not conduct electricity but its aq. soln. NH4OH is a weak electrolyte.

Answer»

Ammonia (gas) is a covalent compound.

As there are no ions present in it, it does or conduct electricity.Ammonia gas dissolves in water to give an aqueous solution of ammonium hydroxide.

NH3 (g) + H2O (l) → NH4OH (aq)

Ammonium hydroxide is a weak electrolyte which ionises to a small extent to give ammonium ions and hydroxide ions.

Due to the presence of these ions an aqueous solution of NH3 gas in water conducts electricity.
