Any help on how to do or start this problem? Even partial solutions would help a lot. Nitrogen in a wastewater treatment plant is in the form of ammonia and ammonium ion and has a total concentration of 7.1 x 10-4 M (KH for NH3 is 57 M/atm; pKa of NH4+ is 9.26). a. Find the fraction of the nitrogen that is in the ammonia (NH3) form (and hence strippable) as a function of pH. Include a table AND a graph. b. If the wastewater pH is raised to 10 and the atmospheric ammonia partial pressure is 5.0 x 10-10 atm, what would be the equilibrium concentration of total nitrogen in the wastewater after air stripping?
