Question

Q12.When sodium is dissolved in liquid ammonia, a solution of deep blue colour is obtained. The colour of the solution is due to (a) ammoniated electron (b) sodium ion (c) sodium amide (d) ammoniated sodium ion​

Answer 1

Explanation:

: (a)M+(x+y)NH3→ M+(NH3)x + e–(NH3)y

The colour of solution (deep blue) is due to the ammoniated electron which absorbs energy in the visible region.

Answer 2

Answer:

When concentration of these solvated ions in the solution of sodium in liquid ammonia is higher, the colour of the solution changes to copper colour. Thus, we can conclude that the colour of the solution is due to the ammoniated electron.
