2) Ammonia (NH3) is an important base, particularly in wastewaters. Consider a solution that
contains a total of 10-3 M of ammonia in water.
NH4+ = NH3 + H+
KA=10-9.3
a) Use the equilibrium expression and concept of mass balance to write an expression for
each of the following species: log [NH4*] and log [NH3].
b) Prepare a log C-pH diagram for the solution described above. Label each line on your
graph with the name of the chemical species it represents. [Notes: Your diagram should
contain 4 lines, one for each of the four species in the system. You may draw your
diagram by hand or using Excel or other software.]
c) Use your diagram to find the equilibrium pH of the solution. Use a circle or “X” to mark
your answer point on the diagram.
d) Now consider a new solution made by adding 10-3 M of NH4Cl to water. Write the
charge balance or proton condition for this solution. Use your diagram to determine the
equilibrium pH of this solution.

Methylamine is used in the manufacturing of several various pharmaceutical products. Atone facility, there is a 2000 lbm tank of methylamine. If the entire tank is releasedcontinuously during a 20-minute time period, determine the concentration in ppm at adistance 1 mile directly downwind. Does this exceed published exposure limits formethylamine? Assume the release is at ground level, and it is an overcast night with a 5mph wind.
