Why argue theory? The values I have for the water solubility of O2 and
CO2 are:
O2: 1.4e-6 mole/cc/atm
CO2: 3.2e-5 mole/cc/atm
In that sense, CO2 is almost 23 times more soluble than O2.
I don't have a diffusion coefficient for CO2 in water. I do have
diffusion coefficients for the other major atmospheric gasses (except
water vapor). They're all in the vicinty of 2 or 3e-5 cm^2/sec. I
wouldn't expect CO2 to be much different.
So what was this all about, anyway?
