Acidic nitrogen hydride

A : H 2 O is the only hydride of chalcogen family which is liquid. R : Acidic nature of hydrides of chalcogen family increases down the group, acidic nitrogen hydride.

The correct answer is N 3 H. Thus, the oxidation state of nitrogen in NH 3 is NH 2 OH. Thus, the oxidation state of nitrogen in NH 2 OH is Last updated on Mar 4,

Acidic nitrogen hydride

Hydrazoic acid , also known as hydrogen azide , azic acid or azoimide , [2] is a compound with the chemical formula HN 3. It is a compound of nitrogen and hydrogen , and is therefore a pnictogen hydride. Hydrazoic acid, like its fellow mineral acids , is soluble in water. The acid is usually formed by acidification of an azide salt like sodium azide. Normally solutions of sodium azide in water contain trace quantities of hydrazoic acid in equilibrium with the azide salt, but introduction of a stronger acid can convert the primary species in solution to hydrazoic acid. The pure acid may be subsequently obtained by fractional distillation as an extremely explosive colorless liquid with an unpleasant smell. Its aqueous solution can also be prepared by treatment of barium azide solution with dilute sulfuric acid , filtering the insoluble barium sulfate. It was originally prepared by the reaction of aqueous hydrazine with nitrous acid :. Other oxidizing agents, such as hydrogen peroxide , nitrosyl chloride , trichloramine or nitric acid , can also be used to produce hydrazoic acid from hydrazine. This reaction is unusual in that it involves compounds with nitrogen in four different oxidation states. In its properties hydrazoic acid shows some analogy to the halogen acids, since it forms poorly soluble in water lead, silver and mercury I salts. The metallic salts all crystallize in the anhydrous form and decompose on heating, leaving a residue of the pure metal.
