Question

The magnetic character and colour observed initially when sodium dissolved in Liq.NH₃ ?

Answer 1

hey there this is your answer...!!!

A small piece of sodium is cut to expose a fresh surface. The sodium is dropped into liquid ammonia at a temperature of approximately −33

0

C. Some of the sodium dissolves, forming sodium cations surrounded by ammonia molecules and electrons surrounded by ammonia molecules. The solvated electrons give the blue color to the solution.

Because of the mobility of the electrons, the solution is a good electrical conductor. Bubbles of hydrogen gas are formed by a second reaction that also produces sodium amide. More concentrated solutions appear bronze-colored and have a conductivity similar to metals and Liquid ammonia remains paramagnetic.

2Na(s)+2NH

(l)→2NaNH
