Abstract
The relations for the calculation of the partial molar volumes of NaCl, NaBPh4, and Ph4AsCl in an aqueous urea solution are obtained. The salt characteristics are divided into ionic components. Different methods of the division are discussed. It is shown that the hydration numbers of Na+ and Cl− ions decrease with increasing urea concentration; therewith, the dehydration of Cl− ion occurs relatively faster.
