Abstract: | Using a hydrogen-electrode thermocell with a temperature difference of 8 K, the initial thermoelectric power in has been determined for aqueous NaOH solutions from 0.003 to 0.2 molal at mean temperatures of 25 and 15°C. Graphs of a function of in vs. a function of m1/2 yield infinitedilution limiting slopes as m1/2 0 which are shown to be in agreement with the five-term theory of this laboratory. Extrapolation of these curves to infinite dilution yields the value for the standard transported entropy of the hydroxide ion. |
