摘要：
In this paper, the concentration and temperature dependences of the density and the viscosity of a system H2O-H2SO4-Al-2(SO4)(3) x18H(2)O in the temperature range of 20-50 degrees C were studied. The sulfuric acid concentration was varied from 2 to 40 wt %, the aluminum sulfate content in the system was varied from 5 to 30 wt %. The viscosity was determined by high precision capillary viscometry, the density was determined by pycnometry. The formulated regression equations can be used for the calculation of the density and the viscosity at different salt and acid concentrations and at different temperatures with the accuracy sufficient for practical purposes, and the results can be presented as reference data.
