What happens when sodium is dissolved in liquid ammonia?

Sodium metal when dissolved in liquid ammonia forms a blue coloured solution.

Does sodium react with ammonia?

Ammonia gas reacts with sodium metal to form sodium amide (NaNH2) and hydrogen gas.

When sodium is dissolved in liquid NH3 the solution becomes blue due to presence of?

– When sodium is added to liquid ammonia, sodium amide compound is obtained and the blue colour formed is associated with the ammoniated electrons, also known as solvated electrons. These electrons are stabilized by various ammonia molecules.

Which of the following is correct for sodium metal in liquid nh3?

The correct option is (d) Liquid ammonia remains diamagnetic. Explanation: The alkali metals dissolve in liquid ammonia without evolution of hydrogen. The colour of the dilute solution is blue and is paramagnetic in nature.

What happens when alkali metals are dissolved in liquid ammonia?

Alkali metals dissolve in liquid ammonia to give deep blue solutions that are conducting in nature. This happens because the alkali metal atom readily loses the valence electron in ammonia solution. Both the cation and the electron combine with ammonia to form ammoniated cation and ammoniated electron.

Does sodium have metallic luster?

The lustre of sodium metal is due oscillation of the loose electron of sodium metal. That’s why sodium has high oxidation potential. The metallic lustre exhibited by sodium is explained by oscillation of a loose electron, which is option ‘b’.

When Na metal dissolves in liquid NH3 gives a deep blue Colour solution explain the reason?

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.

When NA is dissolved in NH3 colour of solution is due to?

blue
The colour of the solution is due to. All alkali metal dissolve in liquid NH3 giving highly conducting deep blue solution. When light fall on these solutions, the ammoniated electrons excite in higher energy level by absorbinf red wavelength and so transmitted light is blue.

When is a piece of sodium added to ammonia a deep blue Colour?

The blue colour is due to. When sodium metal is dissolved in liquid ammonia to form coloured solution. Dilute solutions are bright blue in colour due to the presence of solvated electrons.
