Note 36 — Chapter XX · SULPHUR, SELENIUM, AND TELLURIUM
George Kamensky translation
De la Rive, Pierre, and more especially Roozeboom, have investigated the crystallo-hydrate which is formed by sulphurous anhydride and water at temperatures below 7° under the ordinary pressure, and in closed vessels (at temperatures below 12°). Its composition is SO2,7H2O, and density 1·2. This hydrate corresponds with the similar hydrate CO2,8H2O obtained by Wroblewsky.
