Atmospheric CO2 levels have risen by nearly 20% over the
past 40 years from 320 ppm to 400 ppm. (a) Given that the
average pH of clean, unpolluted rain today is 5.4, determine
the pH of unpolluted rain 40 years ago. Assume that
carbonic acid 1H2CO32 formed by the reaction of CO2 and
water is the only factor influencing pH.
CO21g2 + H2O1l2 Δ H2CO31aq2
