| Abstract | The present paper deals with measurements of the diffusion coefficients as well as the saturated solubilities of single component gases such as N(2), O(2) and CO(2) to a mineral oil. The method to determine the diffusivity is based upon measuring the pressure changes caused by the one-dimensional diffusion between the gas and the oil enclosed in an airtight container. For N(2) and O(2) the profiles of the measured pressure changes agree well with those predicted by diffusion theory, whereas that is not the case with CO(2). Although the reason why CO(2) does not seem to obey diffusion theory has yet to be studied, it may suggest the possibility that the diffusion coefficient varies with the pressure, considering that the range of pressure change in the diffusivity measurement was much obtained by this method fell within ±30% around the average. Moreover the solubility measurements have made clear that Henry's law holds true between the three pure gases and the oils tested, and that O(2) and CO(2) dissolve into the oil approximately two and ten times more, respectively, than N(2). |

| Title Alternative | CHEMICAL STUDIES ON MISASA HOT SPRING (18) A PYRITE-POLYSULFIDE THEORY OF SULFUR SPRING |

| Abstract | In Misasa there occur only few weak sulfur springs, their maximum hydrogen sulfide content being about 5mg per liter. The ground of Misasa consists of granite and there is no active volcano in the vicinity. So the author tried to explain the mechanism of the occurrence of sulfur spring in Misasa by a reaction of the primarily alkaline thermal water upon pyrite. Namely: XFeS(2) + 3Na(2)C(O)3 = 2Na(2)S(1-5) + Na(2)S(2)O(3) + 3CO(2) + XFeS(1-2) Thiosulfate in sulfur spring waters should not be taken for a secondary product from hydrogen sulfide as accepted generally, but is most probably a primary product to the latter. The phenomenon of white turbidity in sulfur spring is caused mainly by the sulfur liberated from the polysulfide decomposed by the change in pH and temperture of thermal waters and not by the sulfur liberated from the oxidation of hydrogen sulfide. Some experimental data were shown to support the theory． |
