Individual Activity Coefficients of H+ and Br-in KBr Solution.
Abstract
The electrode Ag/AgBr/HBr was investigated for the true temperature coefficient of its electrode potential. Measurements at 25 and 35C were extended over the concentration range from about 0.001 m to 0.1 m. Extrapolation to zero ionic strength gives the true temperature coefficient of the standard electrode potential. Comparison of the isothermal temperature coefficients of the cell Ag/AgCl/HCl/Pt-H2/Ag obtained directly, and that obtained by combining the non-isothermal temperature coefficients of the individual electrodes, show good agreement and indicate internal consistency. The activity coefficients of the Cl(-) ion in KCl were computed on the basis of the experimental values obtained in a foregoing investigation under various theoretical approaches and compared with results obtained by other investigators.
