Abstract
The emf method employing concentration cells with liquid electrodes and electrolyte for the determination of zinc activity in the quaternary system has been used. Experiments were conducted on seventy‐five liquid alloys of different mole fractions, with zinc liquid reference electrodes, over the temperature range 714°–877°K. The results were compared with calculated data obtained using Krupkowski's formulas. The zinc isoactivity plots made for constant tin concentration show good agreement between the experimental and theoretical results. Krupkowski's formulas also enable the calculation of the activity coefficients of the remaining components of the quaternary system, namely, tin, cadmium, and bismuth.
