Method/Apparatus/Procedure:
Two procedures were used for saturating solutions with CO
2
:
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 CO
2
generator. The tube and wash bottle were immersed in constant temperature bath. CO
2
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 CO
2
contents of the solutions were determined in the manometric gas apparatus (Refs 1 and 2).
Saturation in rotating tonometer (T).
The technique used was that described by Austin
et al
. (Ref. 3).
Both procedures gave identical results with solutions of acids and salts.
Source and Purity of Materials:
