Question
On dissolving moderate amount of sodium metal in liquid NH3 at low temperature, which one of the folloiwng does not occur?
Options
A.Blue coloured solution is obtained
B.Na+ ions are formed in the solution
C.Liquid NH3 becomes good conductor of electricity
D.Liquid NH3 remains diamagnetic.
Solution
Na + (x + y) NH3 (moderate amount) → [Na(NH3)x]+ + [e(NH3)y]-.
The blue colour solution is attributed to the solvated electrons.
The blue colour solution is highly conducting due to the presence of mainly solvated electrons and solvated Na+ ions.
The blue colour solution is not diamagnetic but paramagnetic due to the presence of solvated unpaired electrons.
