Method/Apparatus/Procedure:
Two procedures were used for saturating solutions with $\ce{CO2}$:
Saturation by bubbling (B).
The solution was placed in the saturating tube, the lower endof which was connected through a wash bottle with a Kipp $\ce{CO2}$ generator. The tube and wash bottle were immersed in constant temperature bath. $\ce{CO2}$ gas was bubbled through it rapidly for 30 minutes. The wash bottle was replaced by a mercury reservoir and the free gas was driven completely out of the saturating tube by admitting mercury underneath the solution. The $\ce{CO2}$ contents of the solutions were determined in the manometric gas apparatus [1,2].
Saturation in rotating tonometer (T).
The technique used was that described by Austin et al. [3].
Both procedures gave identical results with solutions of acids and salts.
Source and Purity of Materials:
