The blue colour of the solution (metal dissolved in liquid ammonia) is due to :

A

free electrons

B

paramagnetic nature of solution

C

ammoniated electrons

D

liberation of hydrogen from solution on standing

Text Solution

Verified by Experts

The correct Answer is:
C
Ammoniated `e^(-)` absorbs energy in the visible region of light and thus imparts blue colour to the solution.
`M+(x+y)NH_(3)rarr[M(NH_(3))_(x)]^(+)+[e(NH_(3))_(y)]^(-)`
`M_((am))^(+)+e^(-)NH_(3)(l)rarrMNH_(2(am))+(1)/(2)H_(2)(g)`
