Un-ionized ammonia (NH3) is toxic to fish at low concentrations. If the maximum allowable concentration of NH3 in a river (CNH3) is 0.20 mg/L as N, what is the maximum concentration of ammonium ion (NH4+) allowed (CNH4+), in units of mg/L as N, when the river water pH is 9? The dissociation of ammonium ion in water has an equilibrium constant of pKa = 9.25 and is described by the reaction: NH4+ = NH3 + H+. Show units throughout the...

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 )

Dissolved ammonia is a common contaminant in drinking water, streams, and rivers. The dissolved form can cause an unpleasant taste in the water and is toxic to many aquatic life forms. Gaseous ammonia (NH3) has an unpleasant odor that has been described as similar to baby diapers or window cleaner. b. Fish are very sensitive to un-ionized ammonia (NH3) and concentrations as low as I .0 mg/L can be toxic. If you took a sample of water downstream of a...

3. (40 points) The mass concentration in mg/L of a carbon compound (C6H12O6N2) measured in a water sample is three times higher than NH3 mass concentration. The ThoD for both carbon and nitrogen oxidation are 384 mg/L. What is the concentration of NH3 (mg/L) in water sample? (Molecular weight: C6H1206Nz=208; NH; = 17; O2 = 32) Assume, NH3 concentration = x mg/L C6H12O6N2 concentration - 3x mg/L NH3 C6H12O6N2 + 02 NH3 + O2 → + CO2 + H2O +...

A treatment plant has the following species in the influent wastewater: NH3-N = 24 mg-N/L, 0.13 mg NO2-N/L, 0.41 mg NO3-N/L, and a pH of 7. Using MINEQL+5.0 available on the COE computers generate a single pC-pH diagram showing the species, NH4+, NH3(aq), NO2-, NO3-, H+ and OH- as a function of pH (from 0.5 to 13.5 in 26 steps). Answer the following question, which nitrogen species is predominating at pH 6 and which is predominating at pH 11?
