Values of γ±KCl over temperature and molality ranges of 10° to 50°C and 0.01 to 1.0 molal were determined with an electromotive-force cell: potas sium-sensitive glass electrode, KCl (molality), Ag-AgCl. A more satisfactory method than is commonly employed was devised for treating the experimental measurements of potential.
