The Formula For Sodium Amide

The Formula For Sodium Amide

Formula of sodium amide

Sodium amide is also known as the sodamide, a very solid inorganic base.

Sodium amide

Formula and structure: Sodium amide chemistry is NaNH2 with a molar weight of 39.01 g / mol. NaNH2 is a tetrahedral crystal structured salt material. The chemical composition consists of the ions of sodium (Na+) as amide (NH2-) and shown below. This molecule is made up of free amide ions.

Preparation: Sodium amide is made with ammonia gas or liquid ammonia by reaction of sodium metal. In liquid ammonia, sodium with iron nitrate catalyst is the typical production method for speeding up this process. The reaction begins with the production of an intermediate electrode that gives sodium amide and hydrogen gas quickly.

2 Na + 2 NH3 + 2 Nas2 + H2, respectively.

Physical properties: Sodium amide exists with a heavy ammonia odour as colourless crystals. The melting point is 210 ° C and the boiling point is 400 ° C. Its density is 1.39 g / mL.

Chemical properties: The sodium amide is extremely sensitive and strongly reactive to ammonia gas and sodium hydroxide. Chemical properties:

NaNH2 + H2O + NaOH NH3

It easily absorbs H2O and CO2 into peroxides that constitute explosive compounds from the air in closed containers. This is why sodium amide is contained in tightly sealed tanks in inert gases (such as argon or nitrogen). To have an ionic conductive solution, NaNH2 dissolves in fluid ammonia. In many organic solvents, it is insoluble.

Application: Sodium amide is a good basis and is used for this reason in many reactions, in particular organics. It is also used for preparing a certain number of dyes and other organic compounds (for example, hydrazine, Sodium hydride) (for example, indigo).

Health effects/safety hazards: Sodium amide has an eruption of peroxides, responds violently to air and water. It also represents a significant health risk. When inhaled, the eyes, mucosal membranes, and respiratory tract can cause serious irritation or even chemical burns. Screwed gastrointestinal burns or intake can lead to fatal burns.
