Highly pure dilute solution of sodium in liquid ammonia

A

Shows blue colour

B

Exhibits electrical conductivity

C

Produce sodium amide

D

Produce hydrogen gas

Text Solution

Verified by Experts

The correct Answer is:
A, B
`Na + (x+y) NH_(3)(l) to underset("solvated cation")([Na(NH_(3))_(x)]^(+))+underset("(blue colour)")underset("solvated electron")([y(NH_(3))_((l))]^(-))`
Due to formation of solvated electron , it shows blue colour and electrical conductance exhibits due to both ions.
