Abstract
The activity of tin in lead-tin binary liquid solution has been measured by the oxygen concentration cell technique at 700.., 800.., and 900... The activity of tin deviates in a positive direction from ideality, with the deviation increasing with decreasing temperature. The activity of lead was obtained by the Gibbs-Duhem equation and it also shows the posi -tive deviation from ideality. The free energy of solution of the lead-tin system as well as the excess free energy of solution was calculated. Also, the partial molal free energies of lead and tin were calculated. The cell employed is as follows: Pb-Sn liquid alloy-SnO2|ZrO2-CaO|Sn-SnO2 (EMT=-RT/nF in asn)Keywords
