Sodium amide, commonly called sodamide (systematic name sodium azanide), is the inorganic compound with the formula NaNH 2. It is a salt composed of the sodium cation and the azanide anion. This solid, which is dangerously reactive toward water, is white, but commercial samples are typically gray due to the presence of small quantities of ...
The alkali metal derivatives are best known, although usually referred to as alkali metal amides. Examples include lithium amide, sodium amide, and potassium amide.These salt-like solids are produced by treating liquid ammonia with strong bases or directly with the alkali metals (blue liquid ammonia solutions due to the solvated electron): [1] [2] [4]
In water, OH − is the strongest base. Thus, even though sodium amide (NaNH 2) is an exceptional base (pK a of NH 3 ~ 33), in water it is only as good as sodium hydroxide. On the other hand, NaNH 2 is a far more basic reagent in ammonia than is NaOH. The pH range allowed by a particular solvent is called the acid-base discrimination window. [1]
Compared to amines, amides are very weak bases. While the conjugate acid of an amine has a pK a of about 9.5, the conjugate acid of an amide has a pK a around −0.5. Therefore, compared to amines, amides do not have acid–base properties that are as noticeable in water. This relative lack of basicity is explained by the withdrawing of ...
In the first step, ammonia is converted to sodium amide by metallic sodium: 2 Na + 2 NH 3 → 2 NaNH 2 + H 2. It is a redox reaction in which metallic sodium gives an electron to a proton of ammonia which is reduced in hydrogen gas. Sodium easily dissolves in liquid ammonia to produce solvated electrons responsible for the blue color of the ...
Sodium hydride: a strong base used in organic synthesis Sodium hydroxide: strong base with many industrial uses; in the laboratory, used with acids to produce the corresponding salt, also used as an electrolyte: Sodium hypochlorite: frequently used as a disinfectant or a bleaching agent Sodium nitrite: used to convert amines into diazo ...
Sodium salts are salts composed of a sodium cation and the conjugate base anion of some inorganic or organic acids. They can be formed by the neutralization of such acids with sodium hydroxide . Categorization
Weak bases, such as baking soda or egg white, should be used to neutralize any acid spills. Neutralizing acid spills with strong bases, such as sodium hydroxide or potassium hydroxide, can cause a violent exothermic reaction, and the base itself can cause just as much damage as the original acid spill.
