Thus far I have calculated the volume of CO2 in the water using NIST solubility values.

I believe the total pressure of the system to be P= PsatW + Po + Pn + Pco2.

The saturation pressure of water is calculated using the Antonine equation

Then the partial pressures of oxygen, nitrogen and CO2 are calculated using the ideal gas eq.

However, I am not sure whether I can apply the ideal gas equation to the dissolved CO2.

Additionally I am not including Henry's Law to account for air dissolved in water as I am assuming the solution is saturated(or near enough) with CO2.

Is there another way of doing this? Does anyone know how to account for the dissolved CO2?

Thanks in advance
