How is the concentration of CO2 dissolved in a liquid measured?
CO2 is dissolved in a solution by some dipole-dipole interactions, and also by acid-base reactions between the slightly acidic CO2 molecule/ neutral water... So, when you see CO2 measurements in L/L or % volume/volume, what is this number actually measuring? The volume/volume of the gaseous CO2 phase with liquid water? Or CO2 in the aqueous phase and liquid water?

Carbon dioxide concentrations, and other gases as well, are usually measured in solutions by gas chromatography. The chromatograph is usually equipped with a thermal conductivity detector, which can detect most materials. Concentration units are the same as any other solution, although I agree a v/v ratio concentration unit is not too useful.
