Alkali metals dissolve in liquid ammonia to give blue coloured solutions. Why?

When sodium metal dissolves in liquid ammonia, it gives a deep blue coloured solution. Explain the reason.

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

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

Give reasons. (i )Solutions of alkali metals in liquid ammonia are blue in colour.

A scientist dissolved sodium metal in liquid NH_3 . He got a coloured solution. When the solution was kept for sometime then observed a gas buddling out. Give the colour of the solution and identify the gas evolved. Discuss the chemistry involved.

A piece of metallic sodium is added to liquid ammonia.blue colour is observed.What is the reason for this?

A solution of a metal ion when treated with KI gives a red precipitate which dissolves in excess KI to give a colourless solution. Moreover, the solution of metal ion on treatment with a solution of cobalt(II) thiocyanate gives rise to a deep-blue crystalline precipitate. The metal'ion is

(a) What happens when alkali metals dissolved in ammonia? (b) Complete the reaction, LiNO_3 overset(heated)rarr 2 NaNO_3overset(heated)rarr
