Thermodynamic behaviour of sulphur in dilute solution range in the liquid binary lead-silver alloys has been studied by the H2S–H2 gas equilibrium method using a closed-circuit recirculation technique. The amount of sulphur dissolved in the binary lead-silver alloy of different compositions equilibrated with H2S–H2 gas mixture of definite composition and at definite temperatures has been determined by the spectrophotometric method. Data obtained on the solubility of sulphur have been used to calculate the free energy, the enthalpy and the entropy of solution of sulphur. Empirical results obtained in the present investigation have been analysed in the light of existing theoretical solution models.
