Molten Salts Electrical Conductivity in the System Silver Chloride – Silver Nitrate

Conductivity and density data have been obtained for the system silver chloride – silver nitrate. The Arrhenius activation energy for electrical migration in molten silver chloride is constant at 1280 cal. mole −1 from 460 to 530 °C.; for silver nitrate there is a variation from 3300 cal. mole −1 at 220 ° to 2700 at 320 °C., which indicates a diminution of structural forces in molten silver nitrate with increase in temperature. The activation energy for binary melts of the two salts at 320 °C. is constant at 2700 cal. mole −1 from 0 to 20 mole % silver chloride; Frenkel's simple equation for the dependence of the activation energy on composition is not supported by this work.
