Ammonia is present in wastewater largely due to human urine. Unionized ammonia
(NH3) is the conjugate base of the ammonium ion (NH4+) with acid dissociation constant (KA) for NH4+ equal to 5.7 × 10−10. Write the acid-base reaction for the deprotonation of the ammonium ion. Assume that a wastewater treatment plant does BOD oxidation only (i.e., no ammonia removal). What is the dominant ammonia species in the wastewater at pH 7: unionized ammonia or ammonium ion? Prove your answer with calculations.

Ammonia (NH3) is somewhat volatile. It is also the conjugate base of the ammonium ion (NH4+). In order to keep the ammonia from volatilizing from a wastewater treatment reactor, it is useful to shift this acid-base equilibrium reaction toward NH4+. The pKa of the ammonium ion is 9.24. In what pH range should the reactor operate?

Nitrogen in a wastewater treatment plant is in the form of ammonia and ammonium ion and has a total ammonia concentration of 7.1 x 10^-4 M at pH = 7. Total ammonia concentration = [NH3] + [NH4^+]. NH3 partial pressure = 5 x 10^-10 atm. KH at 25-degree Celcius is 57 mol/(L x atm). Ka at 25-degree Celcius = 10^-9.26. A. Calculate NH3 and [NH4+] in M at the present condition where pH = 7 at 25 degrees Celcius. B....

Question 53 (1 point) Ammonia , NH3, is a stronger base than the acetate ion, CH3COO". When acetic acid, CH3COOH, reacts with ammonia, NH3, what species are present in the solution in the largest amount? CH3COOH + NH3 CH3COO + NHA acetic acid, CH3COOH, and ammonia, NH3 acetic acid, CH3COOH, and ammonium, NH4* acetate ion, CH3C00, and ammonia, NH3 acetate ion, CH3C00", and ammonium ion, NHA

Ammonia, NH3, is a weak base because a proton can readily bind to the lone pair on the nitrogen to produce the ammonium ion, NH4+. Organic compounds that contain nitrogen are also weak bases for the same reason. Amines are compounds derived from ammonia in which one or more of the hydrogens are replaced by a carbon-containing group (R). The simplest amine is methylamine in which is a "methyl" group, CH3. Its kb is 4.4 X 10-4. Write the balanced...

The acid dissociation constant Ka equals 1.26 x 10-2 for HSO4- and is 5.6 x 10-10 for NH4+. Which statement about the following equilibrium is correct? HSO4-(aq) + NH3(aq) = SO4 2-(aq)+ NH4+(aq) a. The reactants will be favored because ammonia is a stronger base than the sulfate anion. b. The products will be favored because the hydrogen sulfate ion is a stronger acid than the ammonium ion. c. Neither reactants nor products will be favored because all of the...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
