Abstract


The present work is devoted to the study of lead thermodynamic activity in the Pb-Sb-Bi alloys. The method for EMF measurements of the concentration cell: (–)Pb|KCl-PbCl2¦¦KCl-PbCl2|Pb-(Sb-Bi)(+) was used. The obtained concentration dependences of the galvanic cell EMF are described by linear equations. The lead activity in the ternary liquid-metal alloy demonstrates insignificant negative deviations from the behavior of ideal solutions.

Keywords


thermodynamic activity of lead; ternary alloys; electrochemical cell; antimony; bismuth
