Question

Highly pure dilute solution of sodium in liquid ammonia(a) shows blue colour (b) exhibits electrical conductivity(c) produces sodium amide(d) produces hydrogen gas.

Answer 1

To answer this question we will analyse each answer .

A : Shows blue color.

In the dilute solutions of Sodium in ammonia the solvated electrons will have a deep blue color However in more concentrated solutions the solution will have a copper color or bronze color and hence A is correct.

B:Exhibits electrical conductivity

The solution exhibits electrical conductivity since the solvated electron and ions can carry current.

C and D: Produces Sodium amide,Produces Hydrogen

The solution of Sodium in liquid Ammonia is more stable and hence no reaction occurs unless there is the presence of a catalyst.

The correct answers are :

A and B

Answer 2

the answer is it shows blue color
