Question

Explain the following.

Sodium dissolves in liquid ammonia to form a solution which shows electrical conductivity.

Answer 1

1. Sodium dissolves in liquid ammonia giving deep blue coloured solutions which is electrically conducting in nature.
   \[\ce{Na + (x + y)NH3 ->  [Na(NH3)_{{x}}]^+ + [e(NH3)_{{y}}]-}\]
2. Due to the formation of ions, the solution shows electrical conductivity.
