Carbon dioxide is an ubiquitious gas present in the earth’s atmosphere, in the soil air, and in dissolved form in rainwater as well as in groundwater, in rivers, lakes and in the ocean. In dissolved form it constitutes H2 CO3 , carbonic acid, which is the motor of erosion and weathering of rocks. Figure 1.1 shows the CO2 pressure as its negative decadic logarithm for various environments. For CO2 dissolved in water this is the pressure which would be in equilibrium with the aqueous CO2(aq) dissolved.
