Tóm tắt

The structure of aqueous solutions of KBr was studied by viscosimetry and IR spectroscopy at temperatures of 283.15–333.15 K and concentrations of 0.01–0.07 mole fractions. The results of our experiments were used for calculating the activation parameters of viscous flow, the partial molar volume of KBr in solution, and the energies and lengths of hydrogen bonds between water molecules; the concentration dependences of these parameters were analyzed. The results indicate that KBr desrtroys the structure of water.
