N2 - Densities and sound velocities in 0.1 mol · kg-1, 0.5 mol · kg-1, and 1.0 mol · kg-1 sodium carbonate and sodium sulfate solutions were determined at 1 K temperature intervals in the 278.15 K to 323.15 K range. Measured quantities were expressed as polynomials of temperature, and these polynomials were used to evaluate the apparent molar volumes V2, φ(T, m), the isobaric thermal expansibilities α(T, m), the product of temperature and the second-order derivatives of volume with respect to temperature T(∂2V/ ∂T2)P, m (changes in isobaric heat capacities with respect to pressure -(∂Cp/∂P)T, m), the isentropic compressibilities κs(T, m), the isothermal compressibilities ∂T(T, m), the apparent molar compressibilities K2, φ(T, m), the isochoric thermal pressure coefficients (∂P/∂T)V, m, the change of cubic expansion coefficients with pressure at constant temperature (∂α/∂P)T, m, and the second-order derivatives of pressure with respect to temperature T(∂2P/ ∂T2)V, m (changes in isochoric heat capacities with respect to volume (∂CV/∂V) T, m).
