The pH of clean rain is influenced by the partial pressure of CO2 in the atmosphere. In addition, acid rain can be formed when sulfur dioxide (SO2) is discharged into the atmosphere.
i) The atmospheric CO2 concentration could rise to 400 ppmv by 2020? Calculate the pH of clean rain in this scenario.
ii) Now assume that the atmosphere also contains 20 ppbv of SO2 . Calculate the pH of this acid rain?
