Abstract
The effects of various non-hydrolyzing salts on the infra-red spectrum of water have been studied in the region between 1μ and 7μ. Variations in the positions of the absorption maxima at 1.46μ, 1.79μ, 1.96μ, 3.0μ, 4.7μ, and 6.1μ have been observed. The changes produced by the solutes have been compared with existing data on the effects of temperature variation on the absorption of water. The results indicate that, in general, large ions produce changes similar to the changes produced by increasing the temperature of the pure solvent, whereas small ions produce the reverse effect. These results are in agreement with data on the other physical properties of water and aqueous solutions.Keywords
