Zinc chloride vapour pressures, activities and partial molar energies have been determined in the reciprocal fused salt system: Zn,Na/Cl,SO4 over the range 770-900 K. The transpiration vapour pressure of pure ZnCl2 was first redetermined for the range 720-900 K and found to follow the equation (in which P� is in mmHg): �������������� Log P�ZnCl2 = (-8247�17)/T-5.033 log T + 26.213 � 0.006 Activities of ZnC1, in the reciprocal system differed greatly from ideality, the degree of departure varying with both composition and temperature. In general, at relatively high ZnCl, concentrations, observed activities were greater than ideal and ZnCl2 partial molar enthalpies were positive; this behaviour is believed to be largely caused by the effect of partial covalent bonding in pure ZnCl2. At low ZnCl2 concentrations, activities were much less than ideal and ZnCl2 partial molar enthalpies were negative; this other effect is believed to be caused by the formation of complex ions within this system.

The conformal ionic solution model has been applied to the charge asymmetrical, reciprocal fused salt system: Na+,Znz+/C1-,S042-. This model takes into account binary and ternary type interactions as well as the exchange equilibrium: ZnCl2 + Na2SO4 ↔ ZnSO4 + 2NaCl Calculated ZnCl2 activities are found to be in reasonable agreement with experimental values.

Aldosterone Production

ABSTRACT An extract of human urine, which was previously shown to stimulate aldosterone production by rat adrenal sections, was further purified. Evidence was obtained that its aldosterone-stimulating effect was due to the presence of ammonium ions. Addition of ammonium chloride and of urine extract to the incubation medium caused identical increases in aldosterone production in vitro. In addition to ammonium ions, rubidium and caesium ions also stimulated aldosterone production up to 250% that of control values without a significant effect on corticosterone production. Similar dose-response curves were obtained when increasing concentrations of potassium, ammonium, rubidium and caesium ions were tested. Aldosterone production was maximal at concentrations of 7 mval/1 and was significantly lower at higher concentrations. When ammonium chloride and ACTH were simultaneously added to the incubation medium, the production of aldosterone and of corticosterone was lower than with ACTH alone. On the other hand, the stimulating activity on aldosterone and corticosterone production by »TPN« (NADP) and glucose-6-phosphate was enhanced by the simultaneous addition of ammonium chloride.
