When an alkali metal dissolves in liquid ammonia the solution can acquire different colours. Explain the reasons for this type of colour change.

How alkali earth metal dissolve in liquid ammonia ?

When alkali metals react with liquid ammonia the solution obtained is

The alkali metals dissolve in liquid NH_(3) , it is found that:

Why do alkali metals dissolve in liquid ammonia to form blue solution which is conducting in nature?

Alkali metals oxide are obtained by combustion of the metals.Although Na normally gives Na_2O_2 ,it will take up further oxygen at elevated pressure and temperature to form NaO_2 .The per and superoxides of the heavier alkalies can also be prepared by passing stoichiometric amounts of oxygen into their solution in liquid ammonia. The different alkali metal oxides can be distinguished by reaction with water.The superoxides reacts with CO_2 and give oxygen gas.The stability of per and superoxides is based upon that larger cation can stablise larger anion, due to larger lattice energy. Alkali metals dissolve in liquid ammonia.Dilute solutions are dark blue in colour but as the concentration increases above 3M, the colour changes to copper bronze and the solution acquires the metallic lusture due to the formation of metal ions clusters.The solutions of alkali metals in liquid ammonia are good conductors of electricity due to the presence of ammoniated cations and ammoniated electrons.However, the conductivity decreases as the concentrations increases, since ammoniated electrons and ammoniated cation associate. Select the correct choice for alkali metal oxides.

KO_2 is used in oxygen cylinders in space and submarines because it :

When sodium metal is dissolved in liquid ammonia, blue colour solution is formed. The blue colour is due to

The metal that dissolves in liquid ammonia, giving a dark blue coloured solution is
