Zinc nitrate is usually prepared by dissolving zinc metal, zinc oxide, or related materials in nitric acid: Zn + 2 HNO 3 → Zn(NO 3) 2 + H 2 ZnO + 2 HNO 3 → Zn(NO 3) 2 + H 2 O. These reactions are accompanied by the hydration of the zinc nitrate.
N 2 H 4 + HNO 2 → HN 3 + 2 H 2 O. With the hydrazinium cation [N 2 H 5] + this reaction is written as: [N 2 H 5] + + HNO 2 → HN 3 + H 2 O + [H 3 O] + Other oxidizing agents, such as hydrogen peroxide, nitrosyl chloride, trichloramine or nitric acid, can also be used to produce hydrazoic acid from hydrazine.

P2 1 /n. β-Zn(N 3) 2 is trigonal, space group P3 2 21, and γ-Zn(N 3) 2 is monoclinic, space group C2. It is easily hydrolyzed, and attempts to prepare it in aqueous solution resulted in the precipitation of basic azides Zn(OH) 2−x (N 3) x (x = 0.9–1.0). Both the α- and β-forms were found to be very friction- and shock-sensitive ...
In chemistry, azide (/ ˈ eɪ z aɪ d /, AY-zyd) is a linear, polyatomic anion with the formula N − 3 and structure − N=N + =N −. It is the conjugate base of hydrazoic acid HN 3. Organic azides are organic compounds with the formula RN 3, containing the azide functional group. [1] The dominant application of azides is as a propellant in ...
HNO 3 + 2 H 2 SO 4 ⇌ [NO 2] + + [H 3 O] + + 2 HSO − 4; Equilibrium constant: K ≈ 22. The nitronium ion, [NO 2] +, is the active reagent in aromatic nitration reactions. Since nitric acid has both acidic and basic properties, it can undergo an autoprotolysis reaction, similar to the self-ionization of water: 2 HNO 3 ⇌ [NO 2] + + NO − 3 ...
3 Zn(NH 2) 2 → Zn 3 N 2 + 4 NH 3. It can also be formed by heating zinc to 600 °C in a current of ammonia; the by-product is hydrogen gas. [3] [5] 3 Zn + 2 NH 3 → Zn 3 N 2 + 3 H 2. The decomposition of Zinc Nitride into the elements at the same temperature is a competing reaction. [6] At 700 °C Zinc Nitride decomposes. [1]
Zinc borate refers to a family of inorganic compounds consisting of borate of zinc.They are white solids with the formulas 4ZnO·B 2 O 3 ·H 2 O, ZnO·B 2 O 3 ·1.12H 2 O, ZnO·B 2 O 3 ·∼2H 2 O, 6ZnO·5B 2 O 3 ·3H 2 O, 2ZnO·3B 2 O 3 ·7H 2 O, 2ZnO·3B 2 O 3 ·3H 2 O, 3ZnO·5B 2 O 3 ·14H 2 O, and ZnO·5B 2 O 3 ·4.5H 2 O.
Zn + 2 H 2 O + 2 NaOH → Na 2 Zn(OH) 4 + H 2. From such solutions, one can crystallize salts of containing the anions Zn(OH) 4 2−, Zn 2 (OH) 6 2−, and Zn(OH) 6 4−. Na 2 Zn(OH) 4 consists of tetrahedral zincate ion and octahedral sodium cations. [3] The salt Sr 2 Zn(OH) 6 features zinc in an octahedral coordination sphere.
