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 is the chemical compound with the formula Na N O 3.This alkali metal nitrate salt is also known as Chile saltpeter (large deposits of which were historically mined in Chile) [4] [5] to distinguish it from ordinary saltpeter, potassium nitrate.
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 chlorate is an inorganic compound with the chemical formula Na ClO 3.It is a white crystalline powder that is readily soluble in water. It is hygroscopic.It decomposes above 300 °C to release oxygen [4] and leaves sodium chloride.
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.
The standard Gibbs free energy of formation (G f °) of a compound is the change of Gibbs free energy that accompanies the formation of 1 mole of a substance in its standard state from its constituent elements in their standard states (the most stable form of the element at 1 bar of pressure and the specified temperature, usually 298.15 K or 25 °C).
Sodium nitrite is made industrially by passing a mixture of nitrogen oxides into aqueous sodium hydroxide or sodium carbonate solution: [2] [1] NO + NO 2 + 2 NaOH → 2 NaNO 2 + H 2 O NO + NO 2 + Na 2 CO 3 → 2 NaNO 2 + CO 2. The product is purified by recrystallization.
This colourless liquid is prepared by treatment of arsenic(III) oxide with hydrogen chloride followed by distillation: . As 2 O 3 + 6 HCl → 2 AsCl 3 + 3 H 2 O. It can also be prepared by chlorination of arsenic at 80–85 °C, but this method requires elemental arsenic.
