Determination of solutions density by the dilatometric titration method

“…The construction of the device makes it possible to vary the piston position continuously (by small steps); in this connection this experiment was named "dilatometric titration." The resulting dependence of the change of the total volume of the solution on the volume of solutions passed in a lower chamber (or on the concentration of a solution in the lower chamber) is rather informative for the physicochemical analysis of multicomponent systems, in particular, for the determination of regions of domination of various chemical processes [7][8][9][10].…”

“…(5) and (8). In the case of a solution dilution by water the knowledge of only the solution density in the lower chamber ρ lo is required, as the density of pure water of 0.997048 g cm -3 at 25°С is known [11].…”

“…As the ρ lo values for three data sets ( [14], [15], and [16]) have appeared somewhat different, we have fulfilled three series of calculations of ρ = f(ω) by Eqs. (5) and (8) and then calculated the deviation of the calculated density values from the corresponding interpolated published data. The results obtained are shown in Fig.…”
