Chapter 8, Problem 8.98P
A sulfuric acid solution is labeled 8 N (where 1 N = 1 g-equivalent/L, and 1 mol of H2SO4 contains two g-equivalents). The specific gravity of the solution is 1.230, and its heat capacity is 3.00 J/(g·°C). Calculate the specific enthalpy of this solution (kJ/mol H2SO4) at 60°C relative to pure H2O and an infinitely dilute solution at 25°C.

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.

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.
