Abstract
Electrostriction in general is the contraction of material under the influence of an electric field. The electrostriction in electrolyte solutions is not measurable directly but depends on accurate measurements of the densities of the solutions at constant temperature and pressure. The electrostriction around ions in aqueous solutions that has been estimated from fundamental considerations of the electrostatics and mechanics involved has been confined to the conditions of infinite dilution. A large dielectric decrement, down to dielectric saturation, results from such enormous fields. The actual compression of the solvent in electrolyte solutions can be determined from the partial molar volume of the solvent or of the electrolyte, obtained experimentally from the densities of its solutions. A different approach estimates the electrostriction volume, from electrostatic considerations and not from the partial molar volumes.
