Abstract:

The determination of the initial thermal emf at 310 C in the system AgT sub 1AgNO3, NaNO3AgT sub 2 is described for the complete composition range. The thermoelectric power of pure AgNO3 319 vdegree C falls off slightly as the mole fraction of AgNO3 decreases and then rises sharply in dilute solutions. Extrapolation towards zero mole fraction of AgNO3 gives a value of 797 vdegree C. The phenomenological equations are presented in a form well suited to the study of liquid electrolytes. For systems with the particularly simple transference properties of this system, the initial emf is equal to the heat of transport for interdiffusion the Peltier heat in the Soret steady stateT. The present results can be combined with the forthcoming Soret effect data to give the heat of diffusional transport and the entropy of the moving iron. Author
