Definite Role

Direct measurements of the ventilatory response to variations in CO2 tension independent of changes in O2 tension are easily obtained by breathing mixtures of carbon dioxide in 100% oxygen. Direct determination of the respiratory response to O2, however, is not possible due to alternations in CO2 tension resulting from changes in ventilation. Therefore, an attempt has been made to determine this response empirically by a combined analysis of breath-holding and ventilatory data. Comparison of experimentally determined responses to various combinations of O2 and CO2 tensions agree quite well with those predicted by this approach and indicate that oxygen plays a small but definite role in the regulation of eupnic breathing at sea level.

Water Of Hydration

This paper is devoted to the direct determination of the vapor pressures of solutions of the nitrates of silver, of ammonium, and of lithium, at temperatures varying from 30 °C. to 105 °C. and at concentrations varying from 10 to 85 weight % (for lithium nitrate, the limited solubility precluded measurements beyond 65%). From the vapor pressures, the enthalpies of evaporation of water (by a modification of the Clapeyron–Clausius equation), the differential heats of dilution, and the activities of water (as compared with the mole fractions of the solvent) have been calculated. From the results we conclude that the water of hydration of the ammonium and silver ions (if, indeed, these ions are hydrated at all) is very loosely attached, while that of the lithium ion is strongly bound.
