Static-state method. The authors designed a solubility apparatus which is composed of three isothermal pre-saturators, saturator and sampler. A schematic diagram of the apparatus is in the original source. $\ce{CO2}$ was introduced (10 hours) through the pre-saturators and the saturator which contained about 120 g of solvent. The equilibrated sample (about 100 g) was transferred from the saturator into the weighed sampler which contained a weighed amount of standard $\ce{NaOH}$ solution. The sampler was weighed again and shaken to complete the reaction between $\ce{CO2}$ and $\ce{NaOH}$. The excess of $\ce{NaOH}$ and the $\ce{NaHCO3}$ was titrated potentiometrically with standard $\ce{HCl}$ solution. The mass of dissolved $\ce{CO2}$ was calculated from the equation: $$w = c_{\ce{HCl}}(V_{2} - V_{1})M$$ where $w$ = mass of dissolved $\ce{CO2}$, $c_{\ce{HCl}}$ = concentration of $\ce{HCl}$; $V_{1}$ and $V_{2}$ are volumes of the $\ce{HCl}$ solution to the first and second end point, respectively, and $M$ = molar mass of $\ce{CO2}$.<br/>(The authors also report solubilities of $\ce{CO2}$ in 15 mass % glucose/$\ce{H2O}$ and in $\ce{NaCl}$ + 15 mass % glucose/$\ce{H2O}$.)
