What happens when lithium reacts with ammonia?

Lithium amide can be made by treating lithium metal with liquid ammonia: 2Li + 2NH3 → 2LiNH2 + H.

Does lithium dissolve in liquid ammonia?

Solutions obtained by dissolution of lithium in liquid ammonia. The solution at the top has a dark blue color and the lower one a golden color. The colors are characteristic of solvated electrons at electronically insulating and metallic concentrations, respectively.

What happens when alkali metals dissolved in liquid ammonia?

When alkali metals are dissolved in liquid ammonia they give blue colored conducting solution. This solution contain ammoniated electron which absorbs light in visible region and impart blue color to the solution. In the concentrated solution the blue color changes to bronze color and solution becomes diamagnetic.

What happens when sodium reacts with liquid ammonia?

Sodium reacts with ammonia and forms sodium amide, that is, $NaN{H_2}$ and hydrogen gas is released.

How pure is anhydrous ammonia?

Pure ammonia is sometimes referred to as anhydrous ammonia to distinguish it from aqueous solutions of ammonia. For example, household ammonia is actually a solution of at least 90 percent water and less than 10 percent ammonia (NH3). Anhydrous ammonia is prepared commercially from natural gas, air and steam.

Is ammonia soluble in toluene?

The solubility of ammonia in toluene has been measured at 398 K and at pressures up to 340 kPa using a static, synthetic and isochoric technique. The solubility data have also been compared with the result obtained from a direct sampling method.

When sodium metal dissolves in liquid ammonia it gives a deep blue Coloured solution this is due to the formation of?

Sodium metal on dissolution in liquid ammonia gives a deep blue solution due to the formation of ammoniated electrons. The reaction is represented as follows: Ammoniated (solvated) electrons show electronic transition in visible region and the solution becomes deep blue colored.

Why Lithium is the strongest reducing agent?

Lithium ion is small in size and has high ionization enthalpy. Thus, Li has a greater tendency to lose electrons in solution than other alkali metals. The Large amount of hydration energy makes it the strongest reducing agent in spite of its highest ionisation enthalpy.

How is ammonia converted to anhydrous ammonia?

The carbon and oxygen, thru a series of catalyst beds, are combined to form CO₂ which is then stripped out of the process gas stream. The resulting gas stream is then passed through four catalyst “bottles”, at 4000-4600 PSI and 930º F, to combine the nitrogen and hydrogen to form anhydrous ammonia.

What’s the difference between ammonia and anhydrous ammonia?

Household ammonia is a diluted water solution containing 5 to 10 percent ammonia. On the other hand, anhydrous ammonia is essentially pure (over 99 percent) ammonia. “Anhydrous” is a Greek word meaning “without water;” therefore, anhydrous ammonia in ammonia without water.
