The solution of sodium in liquid ammonia is quite stable on its own.
You need to add a small amount of a catalyst such asFeCl3for the sodium to react with the ammonia to form sodium amide and hydrogen gas.
2Na(s) + 2NH3(l)FeCl3m−−−→2NaNH2(NH3)+H2(g) It dosenot ptoduce hydrogen gass and sodium anide
*)In dilutesolutionsofNain ammonia, the solvated electrons have a deep blue colour.
In more concentrated solutions, the solution takes on a bronze/copper colour. When it shows blue colour *)
The equation is
Na(s)+(x+y)NH3(l)→Na+(NH3)x+e−(NH3)
The solution exhibits electricity because the solvated ions and electrons can carry the current.
The conductivity obviously depends on the concentration, but concentrated solutions (> 3 mol/L) are better conductors than liquid mercury. When it exhibits electrical conductivity
