What happens when sodium is added to liquid ammonia?

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

When is sodium dissolved in ammonia?

Sodium is added to liquid ammonia, producing a solution containing solvated electrons. When sodium metal is added to ammonia, some of the sodium dissolves. Each of the dissolving sodium atoms loses an electron and becomes a cation. Both the cation and the free electron are solvated by ammonia molecules.

Why do alkali metals dissolve 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.

Why is sodium in liquid ammonia a reducing agent?

Solution of sodium metal in liquid ammonia is strongly reducing (reduction is gaining of electrons) due to the presence of solvated electrons (the solvated electrons supply electrons for reduction).

When is sodium dissolved in liquid?

When sodium is dissolved in liquid ammonia, a solution of deep blue colour is obtained. The colour of the solution is due to. All alkali metal dissolve in liquid NH3 giving highly conducting deep blue solution.

When sodium is gradually added to liquid NH3 then which of the following property does not change?

The correct option is (d) Liquid ammonia remains diamagnetic. Explanation: The alkali metals dissolve in liquid ammonia without evolution of hydrogen.

What is produced when sodium metal is heated with ammonia?

On heating sodium metal in a current of dry ammonia, the compound formed is. Sodium hydride.

Why is ammonia solution of metals a good conductor of electricity?

Solutions of alkali metals in liquid ammonia are intensely colored and good conductors of electricity due to the presence of solvated electrons (e−, NH3), which are not attached to single atoms. A solvated electron is loosely associated with a cavity in the ammonia solvent that is stabilized by hydrogen bonds.

When sodium is dissolved in liquid ammonia a solution of deep blue Colour is obtained the Colour of the solution is due to?

(D) Ammoniated sodium ion. Hint: This phenomenon is exhibited by all of the alkali metals. In other words, we can say that the blue colour is due to the solvated electron which is released by the sodium metal.

What do you understand by the statement ammonia is a reducing agent?

As you can see, here the Nitrogen atom has one lone pair of electrons which it can donate and oxidize (loss of electrons) itself. The species which accepts this lone pair of electrons will be reduced. Hence, it is a reducing agent.

How do you dissolve sodium metal?

Once sodium metal is dropped into the Epsom solution under stirring, it reacts with water quickly and melts. The molten sodium readily wets efficiently and reacts fast with the Epsom salt solution [10]. Sodium dissolution was generally carried out in a fume hood.

Which of them gives Blue colour in liquid NH3?

The blue colour of the solution is due to ammoniated electrons, which absorb energy in the visible region of light. This is why the solution of sodium in liquid NH3 is blue.
