The ammonia molecule has the formula NH3 in chemistry. Learn about the symbol, molecular structure, general properties, and most common uses of...
2.ammonia- a pungent gas compounded of nitrogen and hydrogen (NH3) binary compound- chemical compound composed of only two elements ammonium,ammonium ion- the ion NH4 derived from ammonia; behaves in many respects like an alkali metal ion ...
associated with defects in the urea cycle enzymes (e.g. ornithine transcarbamylase). Ammonia/Ammonium Microplate Assay Kit is designed to directly measure NH3 and NH4+ in a variety of samples. In the assay, ammonia reacts with hypochlorous acid, which is determined at 620nm, is directly prop...
NH3+H2O→pH9.2NH4++OH- In swine wastewater, the prevalence of either of these ions are determined by the pH of the water, ionic strength and temperature. At pH values above 9.2, free ammonia is the dominant form, while ammonium dominates at lower pH values. While ammonia gas can diffuse...
Ammonia nitrogen (NH3-N) in the water refers to the nitrogen existing as free ammonia (i.e. nonionic ammonia, NH3) or ammonium salt (NH4+), which is represented by mg/L. Ammonia nitrogen in the water is mainly produced from the process of nitrogenous organic compound in the sanitary sewa...
因为:NH4+ = NH3 + H+ 所以,[H+]*[NH3] /[NH4+] = 5.6×10^(-10) ① 而 NH3 + H2O = NH4+ + OH-,所以:[OH-] = [NH4+] ② H2O = H+ + OH- ,有 [H+][OH-] = 1×10^(-14), [H+] = 1×10^(-14)/[OH-] ③ 把这两个结果代入 ① 式,可...
Calculate the (OH-), pH, and percent ionization for 0.238 M ammonia (NH3). NH3 + H2O arrow NH4+ + OH-; Kb = 1.8 x 10-5 Determine the [OH^-] of a 0.22 M ammonia solution. Express your answer using two significant figures. ...

In the control reactor, TAN removal efficiency was 12.98%, where the NH3-N equilibrium touched 1.94 mg of NH3-N/l, and the NH4+ equilibrium reached 76.33 mg of NH4+-N/l with a pH of 7.56. With the rising of the pH, the equilibrium of the reaction tends to increase the concentration...
Total ammonium (NH3 + NH4+) oxidation rates were calculated from oxygen uptake measurements using a substrate to oxygen consumption ratio of 1:1.5 [5, 29]. Total ammonium uptake rates were fitted to a Michaelis–Menten model using the equation: V ¼ ðVmax ´ ½SÞ ´ À ...
