AI Article Synopsis
- - The study examines how the mean molar volume changes due to electrostriction when ions are solvated in various solvents, such as ethanol and glycerol.
- - It highlights that the electrostriction effect is inversely related to the solvent's dipole moment, indicating that more polar solvents are better at resisting volume compression under an electrical field.
- - The research discusses how this reduction in solvent volume may affect the number of solvent molecules surrounding ions during the solvation process.
Article Abstract
The diminution of the mean molar volume on electrostriction, ΔelVS, in the large electrical field of ions solvated by several solvents that are useful for the dissolution of electrolytes is presented. The solvents dealt with are ethanol, trifluoroethanol, 1,2- and 1,3-propanediols, glycerol, 2-butanone, 1,1- and 1,2-dichloroethane, pyridine, benzonitrile, nitromethane, nitrobenzene, formamide, and dimethylformamide. The inverse dependence of the relative molar electrostriction volume on the dipole moment of the solvents is suggestive of the fact that the larger the polarity of the solvents, the more they are able to withstand the compressive effect of the electrical field. The implications of this decrease in solvent volume with regard to the solvation number of ions in these solvents have been dealt with.
