  2. Nitric acid - Wikipedia

    en.wikipedia.org/wiki/Nitric_acid

    A solution of nitric acid, water and alcohol, nital, is used for etching metals to reveal the microstructure. ISO 14104 is one of the standards detailing this well known procedure. [45] Nitric acid is used either in combination with hydrochloric acid or alone to clean glass cover slips and glass slides for high-end microscopy applications. [46]

  3. Methyl nitrate - Wikipedia

    en.wikipedia.org/wiki/Methyl_nitrate

    Methyl nitrate can be produced on a laboratory or industrial scale either through the distillation of a mixture of methanol and nitric acid, or by the nitration of methanol by a mixture of sulfuric and nitric acids. The first procedure is not preferred due to the great explosion danger presented by the methyl nitrate vapour.

    en.wikipedia.org/wiki/Aqua_regia

    Aqua regia (/ ˈ r eɪ ɡ i ə, ˈ r iː dʒ i ə /; from Latin, "regal water" or "royal water") is a mixture of nitric acid and hydrochloric acid, optimally in a molar ratio of 1:3. [ b ] Aqua regia is a fuming liquid.

  6. Azeotrope tables - Wikipedia

    en.wikipedia.org/wiki/Azeotrope_tables

    This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

  8. Dinitrogen pentoxide - Wikipedia

    en.wikipedia.org/wiki/Dinitrogen_pentoxide

    Solutions of dinitrogen pentoxide in nitric acid can be seen as nitric acid with more than 100% concentration. The phase diagram of the system H 2 O − N 2 O 5 shows the well-known negative azeotrope at 60% N 2 O 5 (that is, 70% HNO 3), a positive azeotrope at 85.7% N 2 O 5 (100% HNO 3), and another negative one at 87.5% N 2 O 5 ("102% HNO 3 ...

  9. Ammonia - Wikipedia

    en.wikipedia.org/wiki/Ammonia

    Nitric acid is generated via the Ostwald process by oxidation of ammonia with air over a platinum catalyst at 700–850 °C (1,292–1,562 °F), ≈9 atm. Nitric oxide and nitrogen dioxide are intermediate in this conversion: [44] NH 3 + 2 O 2 → HNO 3 + H 2 O. Nitric acid is used for the production of fertilisers, explosives, and many ...
