PSO2 = (1 atm)(1 x 10-6) = 1 x 10-6 atm
[H2SO3] = KH·PSO2 = (1.0 M/atm)(1 x 10-6 atm) =1 x 10-6 M
Reaction: H2SO3 ↔ H+ + HSO3- Ka1 = 0.017
Ka1 = 0.017 = [H++ ][HSO3- ] / [H2SO3] = [H+ ]2 / 1 x 10-6
[H+ ] = [(0.017)(1 x 10-6)]0.5 = 4.123 x 10-4 M

Calculate the pH of a rain cloud that has equilibrated with 1.0 ppm by volume SO_2.
5. Suppose that a rain cloud is approximately spherical in shape, with radius a, and a roughly uniform volume charge density Pp. Calculate the total energy associated with the cloud if: a = 1 (km) and pu-10 (nc/m ). These dimensions and charge density may approximate those found in a thundercloud. As a result, the energy calculated is that released, at least in part, during a lightning strke. 5. Suppose that a rain cloud is approximately spherical in shape, with...
