I know that carbon dioxide is soluble and forms carbonic acid, but exactly how is solubility measured?
How soluble is carbon dioxide in a 1M solution of sodium hydroxide?

$\begingroup$ Difficult question, because there is the physical solubility of the gas itself which is in equilibrium with all the carbonate species. $\endgroup$– JanDec 19, 2015 at 16:33

1$\begingroup$ The question is really somewhat out of whack. In sodium hydroxide any carbon dioxide is converted to the carbonate anion. In a strong sodium +1 solution sodium carbonate has limited solubility, and will ppt out. So until the NaOH is substantially reacted there really isn't any "dissolved" carbon dioxide. $\endgroup$– MaxWDec 19, 2015 at 18:30

$\begingroup$ If you are still interested in this, do you mean the analytical methodology for quantifying carbon dioxide or the experimental procedure before the carbon dioxide analysis part? $\endgroup$– airhuffJan 28, 2017 at 22:11

$\begingroup$ This is a useful recent article for measuring solubility: pubs.acs.org/doi/10.1021/je200991x. Note that fundamentally solubility is a physical equilibrium but in many instances, it involves chemical reactions. $\endgroup$– MistryAug 29, 2022 at 20:33
