Sulfur dioxide (SO₂) is a gas pollutant that is released during combustion of coal. If the partial pressure of sulfur dioxide in the air above a smoke stack is 0.05 atm and the reactions below dictate how sulfur dioxide equilibrates with water, find the equilibrium pH of a rain drop falling over the smokestack. This may be considered an OPEN system. Solve this problem using the following methods: (i) approximation with the graphical method and simple solutions; and (ii) mathematically by solving the ENE. SO2(g) → SO2 (aq) SO2 (aq) +H₂O H₂SO3 H₂SO3 H+HSO) KH = 1.23 M/atm Note, H₂SO, is the aqueous form of sulfur dioxide KA-1.26 x 10-²

Hard water has a high concentration of calcium and magnesium ions. Focusing on the calcium ion, a common home water -softening process is based on a reversible chemical change that can be expressed by Na2Ze(s)+Ca2+(aq)CaZe(s)+2Na+(aq). Na2Ze represents a solid resin that is like an ionic compound between sodium ions and zeolite ions, a complex arrangement of silicate and aluminate groups; CaZe is the corresponding calcium compound. When, during the day, is this system most likely to reach equilibrium? Why doesnt it reach equilibrium and stay there? Periodically it is necessary to recharge the water softner by running salt water, NaCl(aq), through it. Why is this necessary? What concept is discussed in this chapter does the recharging process illustrate? Zeolite ions are used in home water softners because they have a porous but rigid structure that is weakly attracted to cations, readily allowing an exchange among different ions.
