Sodium amide, ordinarily called sodamide (NaNH2) is the inorganic compound. It is a salt made out of the sodium cation and the azanide anion. This strong, which is hazardously receptive toward the water, is white, yet business tests are commonly dim because of the nearness of little amounts of metallic iron from the assembling procedure. Such contaminations don’t as a rule influence the utility of the reagent. NaNH2 conducts power in the combined express, its conductance being like that of NaOH in a comparable state. NaNH2 has been generally utilized as a solid base in the natural blend. 


Arrangement and structure 


Sodium amide can be set up by the response of sodium with alkali gas, however, it is typically arranged by the response in fluid smelling salts utilizing iron(III) nitrate as an impetus. The response is quickest at the breaking point of the smelling salts, c. −33 °C. A cathode, [Na(NH3)6]+e−, is framed as a response intermediate.


2 Na + 2 NH3 → 2 NaNH2 + H2 


NaNH2 is a salt-like material and in that capacity, takes shape as a limitless polymer. The geometry of sodium is tetrahedral. In alkali, NaNH2 structures conductive arrangements, reliable with the nearness of Na(NH3)6+ and NH2− particles.


Uses of Sodium Amide


Sodium amide is for the most part utilized as a solid base in natural science, regularly in fluid smelling salts arrangement. It is the reagent of decision for the drying of smelling salts (fluid or gaseous). One of the primary points of interest in the utilization of sodium amide is that it mostly works as a nucleophile.


About Sodium Hydride


Sodium hydride is the concoction (chemical) compound with the experimental equation NaH. This antacid metal hydride is essentially utilized as a solid yet burnable base in natural combination. NaH is illustrative of the saline hydrides, which means it is a salt-like hydride, made out of Na+ and H− particles, as opposed to the more sub-atomic hydrides, for example, borane, methane, smelling salts, and water. It is an ionic material that is insoluble in natural solvents (albeit dissolvable in liquid Na), steady with the way that H− stays an obscure anion in an arrangement. As a result of the insolubility of NaH, all responses including NaH happen the outside of the strong. 




  • As a solid base 


NaH is a base of wide degree and utility in natural science. As a superbase, it is fit for deprotonating a scope of even feeble Brønsted acids to give the relating sodium subsidiaries. Run of the mill “simple” substrates contain O-H, N-H, S-H securities, including alcohols, phenols, pyrazoles, and thiols. 


  • As a diminishing operator 


NaH diminishes certain fundamental gathering mixes, yet undifferentiated from reactivity is uncommon in natural science. Strikingly boron trifluoride responds to give diborane and sodium fluoride: 


6 NaH + 2 BF3 → B2H6 + 6 NaF 


Si-Si and S-S bonds in disilanes and disulfides are additionally diminished.


  • Hydrogen storage


Despite the fact that not economically noteworthy sodium hydride has been proposed for hydrogen stockpiling for use in power device vehicles. In one test execution, plastic pellets containing NaH are squashed within the sight of water to discharge the hydrogen.
