Chemistry of the binary NaNO/sub 3/-KNO/sub 3/ system
By chemical analysis of samples taken under carefully controlled conditions, it was shown that the only reaction of any consequence that takes place in the equimolar binary NaNO/sub 3/-KNO/sub 3/ system over the temperature range 500 to 600/sup 0/C is represented by NO/sub 3//sup -/ reversible NO/sub 2//sup -/ + 1/2(O/sub 2/). Over this temperature range there is no evidence of the formation of any anionic oxygen species, such as oxide, peroxide, or superoxide, a concentrations greater than 10/sup -6/ mole/kg. Equilibrium constants for the above reaction have been determined over the temperature range 500 to 620/sup 0/C. The standard free energy for this reaction (..delta..G/sup 0/ = -23,029 + 20.64T) has been derived from the experimental data and is in good agreement with similar data for the single salts.
