In order to determine the thermodynamic properties of sulphur dissolved in molten tin, the equilibrium in the reduction of sulphur in liquid tin by hydrogen gas was investigated for the temperature range 727〜873℃. It was found that the molten tin containing sulphur is regarded as an ideal solution within the limit of the experiment. Experimental results are summarized as follows : numerical formula. Combining these equations with the published ones relating to the equilibrium constant of the formation reaction of hydrogen sulphide gas, the approximate equation expressed as a function of temperature for the dissociation pressure of sulphur dissolving in molten tin between 727° and 873℃ may be represented by the following equations : numerical formula.
