(1) The density of the aqueous phase is 1.16969 g per cm^3, and its total volume
is 1.11424E-06 cm^3.
Apparent molar volumes of the following additional solute(s) (determined from
measured densities of aqueous solutions) were used in these calculations: (DMA+)2SO4.
The apparent molar volumes of one or more solutes containing mono- and di-valent
aminium cations are assumed to be fixed, with the values for the cations taken
from a simple correlation based upon available data.
(2) The surface tension of the aqueous phase is estimated to be 71.94 mN per m.
No surface tension model parameters are available for the component(s) listed
below, (followed by their mole percentage(s) in the mixture):
Maloni (5.96E+01), DMA (7.99E-10), H(Malo-) (1.51E-04), H2(Malo2-) (2.11E-02),
NH4(Malo-) (2.86E-03), (NH4)2(Malo2-) (3.98E-01), (DMA+)OH (1.59E-14), (DMA+)(Malo-)
(2.89E-02), etc.
Surface tension model parameters of the following additional solute(s) (determined
from measured densities of aqueous solutions) were used in these calculations:
(DMA+)2SO4.
(3) The molal osmotic coefficient of the aqueous phase is 0.7879. (It is equal
to -ln(aH2O) / ((MW/1000) * SUM), where aH2O is the water activity, SUM is
the total molality of all solute species, and MW is the molar mass of water
in grams.)
There is no second liquid phase.
