| Popis: | In this work, we have performed a critical review of the thermophysical properties of sulfuric acid–water mixtures. The thermophysical properties analyzed are density, viscosity, refraction index, thermal expansion coefficient, and mass expansion coefficient. The density of the sulfuric acid–water mixture has been measured for different mass fractions (w = 0.1–0.4) over a broad temperature range (T = 273.15–333.15 K). A new parametrization of the density has been performed using a least-squares method. In this parametrization, the number of coefficients has been reduced with respect to previous works. Moreover, this new equation has been analyzed in an extended region of temperature and concentration in the following ranges: w = 0–0.1, T = (233.15–373.15 K). The coefficients of thermal and mass expansion have also been calculated experimentally, and a linear relation of the density has been determined as a function of the variations in temperature and concentration. In addition, viscosity and refraction i... |
