Is there oxygen isotope exchange between dissolved CO2 and H2O?

If you had a sample containing an elevated concentration of $\ce{H2^{18}O}$, and bubbled $\ce{C^{16}O2}$ through it, would some of the oxygen-18 isotope be transferred from water to carbon dioxide?


I am aware that this occurs with hydrogen isotopes and am curious if it works for larger and heavier atoms such as oxygen.




As Todd Minehardt points out, not only can the oxygen be exchanged, but this exchange is applied in aqueous geochemistry.


The exchange occurs through the formation of carbonic acid, given in blue below:


$\ce{CO2 + H2O <=> \color{blue}{H2CO3}}$


Once the carbonic acid molecule is formed, its oxygen atoms effectively become equivalent because they rapidly exchange hydrogen ions with the water solvent. So when the above (dynamically equilibrated) reaction is reversed, any one of the carbonic acid oxygens might end up as a water molecule, including atoms that were originally in the carbon dioxide.
