A Reinvestigation of the Conductance of Aqueous Solutions of Potassium Chloride, Sodium Chloride, and Potassium Bromide at Temperatures from 15° to 45°C

The conductance of aqueous solutions of potassium chloride, sodium chloride, and potassium bromide has been redetermined by the direct-current method at temperatures from 15° to 45°C. It is found that on the whole the present measurements satisfactorily confirm the earlier work reported from this laboratory; however, there were apparently slight errors in the temperature scale at 35° and 45° corresponding to a few hundredth's of a percent in the conductance. Revised values of the conductance, of the limiting ionic conductance and its temperature coefficient, and of the coefficients in the Onsager-Shedlovsky equation are tabulated.
