Question

alkali metal gives blue colour in liquid ammonia which disappear after sometime why?
support your answer with reaction.​

Answer 1

Answer:

The alkali metals like Na,K etc. dissolved in liquid Ammonia giving deep blue coloured solution. ... The solution is paramagnetic due to the presence and in the absence of catalysts and impurities decomposes the blue coloured solution and it gives formation to "Metal amide" and liberation of hydrogen gas.

The solvated electron is responsible for a great deal of radiation chemistry. Alkali metals dissolve in liquid ammonia giving deep blue solutions, which conduct electricity. The blue colour of the solution is due to ammoniated electrons, which absorb energy in the visible region of light

Answer 2

Explanation:

Alkali metals dissolve in liquid ammonia giving deep blue solutions, which conduct electricity. The blue colour of the solution is due to ammoniated electrons, which absorb energy in the visible region of light.
