Solved: An aqueous waste stream that has a maximum

Chapter 6, Problem 6.98

(choose chapter or problem)

An aqueous waste stream that has a maximum concentration of 0.50 M H2SO4 (d 1.030 g/mL at 25 C) will be neutralized by controlled addition of 40% caustic soda (NaOH; d 1.430 g/L) before it goes to the process sewer and then to the chemical plant waste treatment facility. However, a safety review finds that the waste stream could meet a small stream of an immiscible organic compound, which could form a flammable vapor in air at 40. C. The maximum temperature of the caustic soda and the waste stream is 31 C. Could the temperature increase due to the heat of neutralization cause the vapor to explode? Assume the specific heat capacity of each solution is 4.184 J/g K
