Methodology:
A volume $V_{1}$ of carbon dioxide, saturated with water vapor, was introduced into Bunte's burette under atmospheric pressure and at the temperature of 17 °C. A volume $v$ of aqueous $\ce{Li2SO4}$ solution of known concentration was then introduced, and the mixture was stirred until no diminution of volume was observed. When the initial temperature was reached, the volume V was read under the pressure $P$. The volume $V_{1}$ at the partial pressure $P_{1}$ of $\ce{CO2}$ was reduced to volume $V^{\prime}_{1}$ at pressure $P$; ($V^{\prime}_{1} = V_{1}P_{1}/P)$.
The solubility coefficient $S_{1}$ of $\ce{CO2}$ was calculated from the equation: $$S_{1} = \frac{(V^{\prime}_{1} - V)}{v}$$

(a) Calculated by the compiler.
(b) S1 = solubility coefficient of CO2.
S1 = (V'1 - V) / v, where (V'1 - V) is the volume of CO2 dissolved at pressure P, and v is the volume of the aqueous Li2SO4 solution.
The paper contained no definitive information about the pressure P. The measurements probably were made at atmospheric pressure.
(c) k = Sechenov constant, defined by equation lg (So/S1) = kc2, where So and S1 are the solubility coefficients of CO2 in pure water and in Li2SO4 solution, respectively, and c2 is the concentration of Li2SO4 in the aqueous Li2SO4 solution.
