1. Nitrogen in an industrial wastewater is primarily in the form of ammonia (NH3) and ammonium (NH4+) ions. The acid/base equilibrium reaction for ammonia and ammonium is given as: NH4+ → H+ + NH3 Ką = 10-9.26 The total nitrogen concentration in wastewater is given as 2 x 10-3 moles/L (or 28 mg N/L), a. Calculate the concentration of ammonia (NH3) and ammonium (NH4*) ions at pH 10. NH3: moles/L NH4*: moles/L Check b. In ammonia stripping, nitrogen is removed from wastewater by volatilization of NH3. Would ammonia stripping be more effective above or below pH 9? Briefly explain your reasoning.

18. In carrying out a titration of a potassium hydroxide solution with a standard hydrochloric acid solution, a student misread the volume on the burette. That is, the actual volume recorded was smaller than the volume required to reach the end point. How will this error affect the calculated concentration of the potassium hydroxide solution? The calculated concentration will be larger than the actual concentration. b. The calculated concentration will be smaller than the actual concentration. The calculated concentration will be the correct concentration. а. с. d. There is no way to determine how this error will affect the calculation. The calculated concentration will be the actual concentration. е.

In an experiment to determine the amount of aspirin in a tablet, one of the bottles of NaOH used was accidentally left open for 24 hours, which lead to it reacting with carbon dioxide. What will be the effect on the calculated amount of aspirin compared to the actual amount in the tablet and the concentration of the NaOH solution? Calculated amount increases since NaOH concentration will be lower than original. Calculated amount increases since NaOH concentration will be higher than original. Calculated amount decreases since NaOH concentration will be lower than original. Calculated amount decreases since NaOH concentration will be higher than original.
