Let's talk ph swings

I'm pretty sure anything will want to flow from high concentrations to lower lower concentrations. Is this one of the thermodynamic laws? So if the concentration of co2 in the surrounding room is higher in co2 than the water, that is where it will go to equilibrium.

Yes, and the reverse happens too.

Technically, the CO2 in the water doesn't "equal" the CO2 in the air, but it is directly proportional to it.
