Zusammenfassung

The ultrasonic velocities, densities, viscosities, and elec. conductivities of aq. solns. of magnesium nitrate and magnesium acetate have been measured from dil. to satn. concns. at 0 ≤ t/°C ≤ 50. The temp. deriv. of the isentropic compressibility, κs, became zero at 2.28 and 2.90 mol kg-1 for Mg(OAc)2 and Mg(NO3)2 solns., resp., at 25 °C. The total hydration nos. of the dissolved ions were ...
