Density, viscosity, and surface tension of sulfuric acid solutions of formaldehyde
The density was measured pycnometrically, the viscosity was determined with a VPZh-2 viscosimeter with a 0.56 mm capillary, and the surface tension was determined by the Rebinder method. Experimental data were reported, and the interpolation equations derived for the calculation are presented. An equation derived for calculating the thermal expansion coefficient was determined from density data. The linear dependence of the surface tension on the temperature permitted the determination of the total specific surface energy of a liquid using the Gibbs-Helmholtz equation for surface events. It was shown that the temperature coefficient of the surface tension increased with an increase in the concentration of formaldehyde, and decreases with an increase in the concentration of sulfuric acid.
