Method/Apparatus/Procedure:
The degassed solvent flows in a thin film down and absorption helix containing the ethene gas plus solvent vapor at a total pressure of one atmosphere. The volume of gas absorbed is measured in an attached buret system [1].
Source and Purity of Materials:
- Ethene. Prepared from ethanol and phosphoric acid.
- Lanthanum chloride. "AnalaR" material.
- Water. No information given.
Estimated Errors:
Mass concentration (m/v) (1): δk/kg-1 mol = 0.010

Experimental Data
The salt effect parameters were calculated from two measurements. The solubility of ethene in water, S°, and in the one molal salt solution, S. Only the solubility of the ethene in water, and the value of the salt effect parameter are given in the paper. The solubility values in the salt solution are not given.
The compiler calculated the values of the salt effect parameter using the mole fraction gas solubility ratio.

(1) The authors used (l/c)log(S°/S) with c defined as g eq salt per kg of water. For the 1-1 electrolyte the compiler changed the c to an m for m2/mol kg-1. The ethene solubility S is cm3 (STP) kg-1.
