Question

Why does the solution of alkali metal becomes bule in liquid ammonia ? give the chemical equation also.

Answer 1

Answer:

The blue colour of the solution is due to ammoniated electrons, which absorb energy in the visible region of light.

Sorry but i don't know the equation.

Answer 2

Answer:

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.

Explanation:

When an alkali metal dissolve in liquid ammonia, the solution can acquire different colors,I mean dilute solutions of alkali metals in liquid ammonia exhibit dark blue color this is because of ammoniated electrons absorb energy in the visible region of light.
