Problem

The oxides of concern in a coal-burning power plant are sulfur oxides, not nitrogen oxides. The diagram for SO2 is shown below (not drawn to scale).

a. What is the lowest temperature at which liquid SO 2 exists?

b. Which is more dense: solid SO2 or liquid SO2?

c. What is the normal melting point of SO2(s)?

d. Suppose you start with a sample of SO 2 at 0.5 atm and -50°C, and decrease the pressure to 0.001 atm while maintaining the temperature at -50°C. What phase changes, if any, will occur?

e. What acid do you expect to form if SO 2(g) is dissolved in water? ____________________
