Infobox references. Ammonia solution, also known as ammonia water, ammonium hydroxide, ammoniacal liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or (inaccurately) ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH 3 (aq). Although the name ammonium hydroxide suggests a salt with the composition [NH+4] [OH− ...
Ammonia is an inorganic chemical compound of nitrogen and hydrogen with the formula N H 3. A stable binary hydride and the simplest pnictogen hydride , ammonia is a colourless gas with a distinctive pungent smell.
The (s) notation indicates equilibrium temperature of vapor over solid. Otherwise temperature is equilibrium of vapor over liquid. log10 of anydrous ammonia vapor pressure. Uses formula shown below. Vapor-pressure formula for ammonia: [4] log 10P = A – B / (T − C), where P is pressure in k Pa, and T is temperature in kelvins;
Ammonium is a modified form of ammonia that has an extra hydrogen atom. It is a positively charged (cationic) molecular ion with the chemical formula NH+ 4 or [NH4]+. It is formed by the addition of a proton (a hydrogen nucleus) to ammonia (NH3).
Ammonia production takes place worldwide, mostly in large-scale manufacturing plants that produce 183 million metric tonnes [1] of ammonia (2021) annually. [2][3] Leading producers are China (31.9%), Russia (8.7%), India (7.5%), and the United States (7.1%). 80% or more of ammonia is used as fertilizer. Ammonia is also used for the production ...
Ammonium sulfate is made by treating ammonia with sulfuric acid: 2 NH3 + H2SO4 → (NH4)2SO4. A mixture of ammonia gas and water vapor is introduced into a reactor that contains a saturated solution of ammonium sulfate and about 2% to 4% of free sulfuric acid at 60 °C. Concentrated sulfuric acid is added to keep the solution acidic, and to ...
Selective catalytic reduction. CATALYTIC REDUCTION. Selective catalytic reduction (SCR) means of converting nitrogen oxides, also referred to as NO. x with the aid of a catalyst into diatomic nitrogen (N. 2), and water (H. 2O). A reductant, typically anhydrous ammonia (NH. 3), aqueous ammonia (NH. 4OH), or a urea (CO (NH.
Ammonium carbonate is a chemical compound with the chemical formula [N H 4]2 C O 3. It is an ammonium salt of carbonic acid. It is composed of ammonium cations [NH4]+ and carbonate anions CO2− 3. Since ammonium carbonate readily degrades to gaseous ammonia and carbon dioxide upon heating, it is used as a leavening agent and also as smelling salt.
