Acid rain depends on exposure of cloud water to sulfur-containing solutions, such as sulfuric acid (H2SO4). Assume that H2SO4 concentrations is air is 20 ug/m3, which is a realistic value for the polluted East Coast, and cloud liquid is 0.002 L/m3. What is the pH of the rainwater assuming all the sulfuric acid is in the liquid water droplet? Hint: The "per m3" means per m3 of air for both [H2SO4] and the cloud liquid water.
