Nitrogen trichloride, also known as trichloramine, is the chemical compound with the formula NCl 3.This yellow, oily, and explosive liquid is most commonly encountered as a product of chemical reactions between ammonia-derivatives and chlorine (for example, in swimming pools).
Sodium nitrate has also been investigated as a phase-change material for thermal energy recovery, owing to its relatively high melting enthalpy of 178 J/g. [14] [15] Examples of the applications of sodium nitrate used for thermal energy storage include solar thermal power technologies and direct steam generating parabolic troughs. [14]
English: Structural formula of the nitrogen trichloride molecule, NCl3, with a nitrogen-chlorine bond of length 1.759 Å and a Cl-N-Cl angle of 107.1 °. Structural information (determined by gas-phase electron diffraction) from CRC Handbook, 91st edition, page 9–25.
sodium chromate Na 2 CrO 4 is made yellow by the chromate ion CrO 2− 4. potassium dichromate K 2 Cr 2 O 7 is made red-orange by the dichromate ion Cr 2 O 2− 7. cobalt(II) nitrate hexahydrate Co(NO 3) 2 ·6H 2 O is made red by the chromophore of hydrated cobalt(II) [Co(H 2 O) 6] 2+. copper(II) sulfate pentahydrate CuSO 4 ·5H 2 O is made ...
Nitrate chlorides are mixed anion compounds that contain both nitrate (NO 3 −) and chloride (Cl −) ions. Various compounds are known, including amino acid salts, [ 1 ] and also complexes from iron group , rare-earth , and actinide metals.
Nitrogen trifluoride can be prepared from the elements in the presence of an electric discharge. [10] In 1903, Otto Ruff prepared nitrogen trifluoride by the electrolysis of a molten mixture of ammonium fluoride and hydrogen fluoride. [11]
Nitrosyl chloride is the chemical compound with the formula NOCl. It is a yellow gas that is commonly encountered as a component of aqua regia, a mixture of 3 parts concentrated hydrochloric acid and 1 part of concentrated nitric acid.
Indium(III) nitrate hydrate is produced by the dissolution of indium metal in concentrated nitric acid followed by evaporation of the solution: [1] [2] [3] In + 4 HNO 3 → In(NO 3) 3 + NO + 2 H 2 O. The hydrate first decomposes to a basic salt and then to indium(III) oxide at 240 °C.
