A new method for determining the speciation of dissolved and hydrolyzed CO//2 in aqueous solutions has been developed. Values of ion pairing constants between HCO//3** minus and Ca**2** plus , Mg**2** plus and Zn**2** plus are presented for temperatures between 10 and 90 C. Use is made of the Fuoss equation of electrostatic ionic interactions to calculate a temperature dependence for the constants. The principal difference between these experiments and earlier ones is that equilibrium constants for reactions between metal ions and HCO//3** minus can be calculated simply by changes in the pH.
