Method/Apparatus/Procedure:
Setchenow (Ref. 1) based his apparatus on those of Fernet (1857) and of Meyer (1857). The manometer was based on ideas he learned from Regnault in 1861. The one meter manometer had three branches, two for measuring the pressure and one a mercury reservoir. The manometer was connected to the absorption cell by a flexible silver capillary. The absorption cell was of two bulbs with a mark in the constricting connection. CO
2
gas was generated, saturated with water vapor and filled the bulbs and manometer to a known pressure less than atmospheric. The liquid was degassed by heating and then passed by the pressure difference into the lower bulb to the mark of known volume. The system was sealed, turned 90 degrees and shaken until equilibrium was established. The gas volume absorbed was reduced to 0 °C and one meter Hg pressure. The Bunsen coefficient was calculated.
Source and Purity of Materials:
(1) Apparently generated from limestone and sulfuric acid. Dried.
(2) Not specified, assumed to be distilled.
Estimated Errors:
Temperature: The author makes a qualitative statement that the results are good to the second decimal.
