Abstract A graphical method, based on a set of acid-base titrations, is
presented for the determination of the carbon dioxide speciation in
natural solutions. The application of this method, in conjunction
with measurements of the partial pressure of carbon dioxide with
which our solutions were in equilibrium permitted the calculation
of the solubility of carbon dioxide.
The results of these calculations in dilute solutions of 1.00
meq/l alkalinity gave a value of 0.070 for the solubility at 25° C.
This value is considerably higher than that obtained by Harned and
Davis (1943), 0.0345, for solutions of zero alkalinity. Our experimental
method, with the conditions used by Harned and Davis, yielded
a result which agreed well with theirs.
It is concluded that the solubility of carbon dioxide within the
alkalinity range found in many fresh waters, is greater than was
previously believed. The reason for this higher solubility is not
known. It is shown that it cannot be ascribed to a specific cation
effect.
