I am conducting a bunch of experiments for my dissertation, and needed to mix a bunch of chemicals like surfactants and polymers into carbonated water. I have been looking online for a while, but can't find any information regarding how the solubility of components (any) change when water is saturated with CO2. Will it be an effect that prohibits the dissolution of different substances significantly as compared to still water?

Also, if you have know of any research papers or such regarding this, I would greatly appreciate you linking them in your answer. If not, that is also totally ok.



If I was not clear enough or more info is needed, just ask, but again, I am not asking for an exact answer, just for a qualitative answer of how big the effect would be.

Thanks in advance.

I imagine soft drink manufacturers know a lot about this - but they may not publish much!

The CO2 is expected to have very little effect on solubilities unless you are working at high concentrations of solutes. At low concentrations, solutes only interact if there is a common component (usually an ion - common ion effect).

But CO2 does make water more acidic by reacting with it:

H2O + CO2  HCO3-  +  H+

So any solubilities that are changed by lowering pH may change.
