At 15.6 °C (60.1 °F), the density of a saturated solution is 0.88 g/ml; it contains 35.6% ammonia by mass, 308 grams of ammonia per litre of solution, and has a molarity of approximately 18 mol/L. At higher temperatures, the molarity of the saturated solution decreases and the density increases. [ 8 ]
The hazards of ammonia solutions depend on the concentration: 'dilute' ammonia solutions are usually 5–10% by weight (< 5.62 mol/L); 'concentrated' solutions are usually prepared at >25% by weight. A 25% (by weight) solution has a density of 0.907 g/cm 3 , and a solution that has a lower density will be more concentrated.
Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH 3 CO) 2 O. Commonly abbreviated Ac 2 O, it is the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis. It is a colorless liquid that smells strongly of acetic acid, which is formed by its reaction with ...
Hydroxylamine (also known as hydroxyammonia) is an inorganic compound with the chemical formula N H 2 OH.The compound exists as hygroscopic colorless crystals. [4] Hydroxylamine is almost always provided and used as an aqueous solution or more often as one of its salts such as hydroxylammonium sulfate, a water-soluble solid.
Skeletal formula of 2-pentyne: ... 2-Pentyne can be synthesized by the rearrangement 1-pentyne in a solution of ethanolic potassium hydroxide or NaNH2/NH3. [1]
Vapor-pressure formula for ammonia: [4] log 10 P = A – B / (T − C), where P is pressure in kPa, and T is temperature in kelvins;
Phthalimide is the organic compound with the formula C 6 H 4 (CO) 2 NH. It is the imide derivative of phthalic anhydride. It is a sublimable white solid that is slightly soluble in water but more so upon addition of base. It is used as a precursor to other organic compounds as a masked source of ammonia. [2]
