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

Raju found that when a zinc rod is immersed in CuSo_4 solution taken in a beaker, the blue colour of the solution faded. Find the reason for the colour change.

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.

When CuSO_4 is mixed with excess of NH_3 , a deep blue coloured solution is obtained.Give the oxidation number and coordination number of the central metal atom of the deep blue coloured compound.

When CuSO_4 is mixed with excess of NH_3 , a deep blue coloured solution is obtained.Write the formula of the compound formed.

A student is doing an experiment in the laboratory using sodium. Suddenly, a piece of sodium falls into liquid ammonia. (a) What changes can you observe in liquid ammonia? (b) What is the reason for the change? (c) If the solution is kept for a long time it is changed into bronze colour. Why?
