    Freshly prepared aqua regia to remove metal salt deposits Freshly prepared aqua regia is colorless, but it turns orange within seconds. Here, fresh aqua regia has been added to these NMR tubes to remove all traces of organic material.

  4. Nitric acid - Wikipedia

    en.wikipedia.org/wiki/Nitric_acid

    Nitric acid is an inorganic compound with the formula H N O 3.It is a highly corrosive mineral acid. [6] The compound is colorless, but samples tend to acquire a yellow cast over time due to decomposition into oxides of nitrogen.

  7. Ostwald process - Wikipedia

    en.wikipedia.org/wiki/Ostwald_process

    The Ostwald process begins with burning ammonia.Ammonia burns in oxygen at temperature about 900 °C (1,650 °F) and pressure up to 8 standard atmospheres (810 kPa) [4] in the presence of a catalyst such as platinum gauze, alloyed with 10% rhodium to increase its strength and nitric oxide yield, platinum metal on fused silica wool, copper or nickel to form nitric oxide (nitrogen(II) oxide) and ...

  8. Ammonia - Wikipedia

    en.wikipedia.org/wiki/Ammonia

    Urea, in the Bosch–Meiser urea process and in Wöhler synthesis; ammonium perchlorate, ammonium nitrate, and ammonium bicarbonate; Cisplatin ([Pt(NH 3) 2 Cl 2) is a widely used anticancer drug. Ammonia is a ligand forming metal ammine complexes. For historical reasons, ammonia is named ammine in the nomenclature of coordination compounds.

  9. Urea - Wikipedia

    en.wikipedia.org/wiki/Urea

    The structure of the molecule of urea is O=C(−NH 2) 2.The urea molecule is planar when in a solid crystal because of sp 2 hybridization of the N orbitals. [8] [9] It is non-planar with C 2 symmetry when in the gas phase [10] or in aqueous solution, [9] with C–N–H and H–N–H bond angles that are intermediate between the trigonal planar angle of 120° and the tetrahedral angle of 109.5°.
