You have measured the pH of rainwater on your campus to be 4.2. Assuming that the acidity in the rainwater is caused by SO2,calculate the concentration of SO2 that must be in the air in the vicinity of your campus. Could you answer the concentration of SO2 in ppm ( The answer from answer key is 0.11 ppm)
