Densities of aqueous solutions of zinc sulfate at molalities ranging from 0.1 to 3.0 mol·kg^–1 were measured with a commercial vibrating tube densimeter at temperatures from 298.15 to 393.15 K and at pressures up to 10 MPa. Comparison between the present values and literature data showed a good agreement in general; however, a direct comparison could be made only at 298.15 K. Isothermal compressibilities derived from the density measurements as a function of pressure also compared favorably with literature values based on speed-of-sound measurements.

硫酸锌水溶液在298.15至393.15 K和最高10 MPa的压力下的体积特性

使用商业振动管密度计在298.15至393.15 K的温度和最高10 MPa的压力下测量了浓度范围为0.1至3.0 mol·kg ^–1的硫酸锌水溶液的密度。目前值与文献数据之间的比较总体上显示出很好的一致性；但是，只能在298.15 K时进行直接比较。从密度测量值得出的等温压缩率随压力的变化也与基于声速测量的文献值进行了比较。
