Sodium chloride / ˌ s oʊ d i ə m ˈ k l ɔːr aɪ d /, [8] commonly known as edible salt, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chlorine ions. It is transparent or translucent, brittle, hygroscopic , and occurs as the mineral halite .
Note: ρ is density, n is refractive index at 589 nm, [clarification needed] and η is viscosity, all at 20 °C; T eq is the equilibrium temperature between two phases: ice/liquid solution for T eq < 0–0.1 °C and NaCl/liquid solution for T eq above 0.1 °C.
Saline solution for irrigation. Normal saline (NSS, NS or N/S) is the commonly used phrase for a solution of 0.90% w/v of NaCl, 308 mOsm/L or 9.0 g per liter. Less commonly, this solution is referred to as physiological saline or isotonic saline (because it is approximately isotonic to blood serum, which makes it a physiologically normal solution).
Hydroxylammonium chloride is a chemical compound with the formula [NH 3 OH] + Cl −.It is the hydrochloric acid salt of hydroxylamine (NH 2 OH).Hydroxylamine is a biological intermediate in nitrification (biological oxidation of ammonia with oxygen into nitrite) and in anammox (biological oxidation of nitrite and ammonium into dinitrogen gas) which are important in the nitrogen cycle in soil ...
One important invention that resulted from the discovery of the mineral acids is aqua regia, a mixture of nitric acid and hydrochloric acid in a 1:3 proportion, capable of dissolving gold. This was first described in pseudo-Geber 's De inventione veritatis ("On the Discovery of Truth", after c. 1300 ), where aqua regia was prepared by adding ...
C 2 H Cl 3 O 2: Molar mass: 163.38 g·mol −1 Appearance Colorless to white, crystalline solid Odor: Sharp, pungent [1] Density: 1.63 g/cm 3: Melting point: 57 to 58 °C (135 to 136 °F; 330 to 331 K) [2] Boiling point: 196 to 197 °C (385 to 387 °F; 469 to 470 K) [2]
The following species and equilibria are present in NaOCl/NaCl solutions: [21] HOCl(aq) ⇌ H + + OCl − HOCl(aq) + Cl − + H + ⇌ Cl 2 (aq) + H 2 O Cl 2 (aq) + Cl − ⇌ Cl − 3 Cl 2 (aq) ⇌ Cl 2 (g) The second equilibrium equation above will be shifted to the right if the chlorine Cl 2 is allowed to escape as gas.
Peracetic acid (also known as peroxyacetic acid, or PAA) is an organic compound with the formula CH 3 CO 3 H. This peroxy acid is a colorless liquid with a characteristic acrid odor reminiscent of acetic acid. It can be highly corrosive. Peracetic acid is a weaker acid than the parent acetic acid, with a pK a of 8.2. [2]
