Abstract
Abstract
EMF measurements were performed on a chemical cell containing a silver and a nitrate electrode. The systems NaNO3 + AgNO3 , LiNO3 + AgNO3, and pure AgNO3 were investigated in a temperature range of 240 °C to 310 °C and in the total concentration range permitted by the phase diagram. We found a linear dependence of the EMF on temperature. Six constants, characteristic for the investigated molten salts depending neither on composition nor on temperature, were determined by the analytical construction of the activity coefficients. Together with the analytically constructed excess molar Gibbs function, the excess molar entropy was calculated from calorimetric data in the literature.
