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. If the wastewater pH is raised to 9, calculate equilibrium [NH3] and [NH4] in M.

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? Show calculations to validate...

Ammonia exists in two forms, ammonium ion (NH4+) and ammonia gas (NH3). In solution, they are related by the reaction Nh4=H+NH3 pK=9.24 If the pH is 8.5 and the total ammonia concentration (ct) is 40 mg/L as N, calculate the concentration of dissolved ammonia gas (NH3) concentration id mg/L (Answer is 7.33 mg/L )

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?

2. Nitrifying bacterial communities are essential in the removal of ammonia (NH3) from municipal wastewater. The bacteria obtain energy for their metabolism by catalyzing the following overall reaction: NH3+202NO3 +H20+H+ The bacteria are able to use NH3 but not NH for this process. a.

Ammonia (NH3) is toxic to fish at a concentration of 0.01 mg/L NH3-N, but ammonium (NH:) has negligible toxicity. What is the maximum concentration (in mg/L) of total ammonia nitrogen (the sum of ammonia and ammonium) that can be in solution without causing toxicity at (a) pH 8 and at (b) pH 10? Note: "NH3-N" and "ammonia nitrogen" means that only the mass of the nitrogen atom is counted. That is, this is treating both ammonia and ammonium as having...
