Solution: An aqueous waste stream with a maximum concentration of 0.50 M H 2SO4 (d = 1.030 g/mL at 25°C) is neutralized by controlled addition of 40% NaOH (d = 1.430 g/L) before it goes to the process sewer and

Problem

An aqueous waste stream with a maximum concentration of 0.50 M H 2SO4 (d = 1.030 g/mL at 25°C) is neutralized by controlled addition of 40% NaOH (d = 1.430 g/L) before it goes to the process sewer and then to the chemical plant waste treatment facility. 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 reached by the NaOH solution and the waste stream is 31°C. Could the temperature increase due to the heat transferred by the neutralization cause the organic vapor to explode? Assume that the specific heat capacity of each solution is 4.184 J/g⋅K.
