Standard enthalpy change is obtained from the temperature dependence to be δH° = 79 kcal/ mol for the reaction of SiO 2 (solid) = Si (melt) + 2O (in melt), which is consistent with the known values of other oxygen related reactions. The solubility extrapolated to the melting point ...
Solubility of oxygen in aqueous electrolyte solutions The solubility of oxygen in a number of aqueous electrolyte solutions was determined using a colorimetric method based on the oxidation of indigo carmine. The effects of changes in electrolyte concentration, temperature and partial press... E Narita...
By applying a more complete analysis to their data which includes diffusion in the cell, it is concluded that: (a) the affinity coefficient of the leaf for CO2is 0.1 to 1.1 micromolar; (b) the temperature dependence of this affinity coefficient cannot be determined from existing data, but ...

The contributions of the solubility and permeation of the ionomer thick film can be separated using the microelectrode technique (see the “Methods”). The measured oxygen solubility and diffusion coefficient are summarized in Fig. 4c and d, respectively. The solubility in the HOPI is two to ...
the result of the small Pi impurities in the lime. A concentration of 0.5 mg P g−1lime, as found in the samples we analysed, is not unusual33. The lower HCl P concentrations in the −L treatments might also result from the increased solubility of HCl P, i.e. mineral P ...
2 (1:2), compared with an atmospheric ratio of approximately 1:4. The solubility of oxygen in water is temperature-dependent, and about twice as much (14.6 mg/L) dissolves at 0 °C than at 20 °C (7.6 mg/L).[10][47] At 25 °C and 1 standard atmosphere (101.3 kPa) of air,...
Dissolved oxygen in both beakers is determined by the PO2to which the liquid is exposed and the solubility of oxygen in plasma. The solubility is .003 ml O2/dl plasma/mm Hg. But what is the PO2? Because there is no CO2exchange taking place in either beaker (as there is in our lung...
solubility, and gas transport); (3) the cell/tissue system (e.g., size of cells, shape and size of tissue structures, and kinetics of tissue formation and ECM formation); and (4) the reactor configuration and the associated fluid mechanic properties (e.g., geometry (symmetry vs. asymmetr...
In detail, the insufficient supplement of O2 limits the solubility in the internal electrolyte and thus affects the ORR reaction rate especially at high discharge current density. In addition, the adjustment of a specific area, oxygen transfer resistance, and membrane thickness could also obtain the...
