The Conductance of Potassium Chloride, Potassium Bromide and Potassium Iodide in Aqueous Solutions from 5 to 55°

The equivalent conductivities of dilute solutions of potassium chloride, potassium bromide, and potassium iodide have been measured at various temperatures, and extrapolated to infinite dilution. These results, when combined with those of A. R. Gordon and others, yield limiting equivalent conductivities of each of the three potassium salts at 10° intervals between 5 and 55°C.

EXTRAPOLATION OF APPARENT MOLAL PROPERTIES OF STRONG ELECTROLYTES

adequately represented the avaiiable activity coefficient data6 for binary aqueous solutions of simple strong electrolytes, and that the inclusion of higher terms6* in the development of the theory would permit its application to solvents of lower dielectric constants, and to electrolytes of more complex valence types. EQUATION 1, or its counterpart in terms of the osmotic coefficient, has long been generally employed for both interpolation and extrapolation of activity coefficient, or osmotic coeEcient, data. Equations for other thermodynamic properties can be derived from this equation by appropriate differentiation. Two such equations, which we will have occasion to use, represent the relative partial molal volume and relative partial molal heat content. These equationss
