چکیده انگلیسی
Densities of solutions of sodium bromide, sodium perchlorate, sodium tetraphenylborate, and tetraphenylphosphonium bromide in methanol at the temperatures ranging from 283.15 to 313.15 K have been measured. Ultrasound velocities for the above systems at T = 298.15 K have been determined. From the obtained data, the partial molar volumes and the partial molar isentropic compressibilities for electrolytes in solution have been estimated. Division into the ionic contributions has been proposed on the basis of the reference electrolyte method. The existence of the high-volume intermediate shell with an enhanced structure has been suggested.
