Potassium-sodium ratios in aqueous solutions and coexisting silicate melts.
Silicate melts were equilibrated with aqueous chloride solutions at temperatures between 770 degrees and 880 degrees C and a total pressure of 1.4 to 2.4 kilobars. The ratio of potassium to sodium in the aqueous phase was (0.74 +/- 0.06) times the corresponding ratio in the coexisting melt over the entire range of temperature and pressure for all chloride concentrations between 0.2 and 4.2 moles per kilogram.
