Abstract A thermodynamic model is presented to calculate the oxygen solubility in pure water (273–600 K, 0–200 bar) and natural brines containing Na+, K+, Ca2+, Mg2+, Cl−, SO42−, over a wide range of temperature, pressure and ionic strength with or close to experimental accuracy. DO solubility tables can be accessed via the U.S. Geological Survey’s DOTABLES software (USGS, 2013b) which are based on equations from Benson and Krause (1980; 1984).” SESDPROC-106-R3, Field Measurement of Dissolved Oxygen, replaces SESDPROC-106-R2 . dissolved oxygen meters by entering feet above sea level, or in some meters, an internal barometer compensates for changes in pressure automatically – provided that the barometer is properly calibrated.

See table … At 20 °C, the concentration of dissolved oxygen in water exposed to gaseous oxygen at a partial pressure of 101.3 kPa (760 torr) is 1.38 × 10 −3 mol L −1. L: N/A : 0.0013: 1700. The experimental data of oxygen solubility (C O 2) and diffusion coefficient (D O 2) in Nafion ® 211 membrane, as an example, are listed in Table 1.11. Dissolved oxygen values shown in the table represent “saturation” for the corresponding temperature. Use Henry’s law to determine the solubility of oxygen when its partial pressure is 20.7 kPa (155 torr), the approximate pressure of oxygen in earth’s atmosphere. Water solubility of oxygen at 25 o C and pressure = 1 bar is at 40 mg/L water. : Solution Step two: Multiply .80 (which is the DO %) by 9.09 (value from oxygen solubility table at 0 salinity and 20º C) = 7.27 mg/L. K from missing citation was used to derive k H and -Δ k H /R. Appendix A - oxygen solubility table .....72 Appendix B – Calibration Values for Various Atmospheric Pressures and ... blood oxygen measurements could be taken real-time in the operating room rather than having a sample drawn and taken to a lab for analysis. Above T = 303. New!! Solubility of oxygen and oxygen compounds. There are also a large amounts of compounds that react with water. the DO solubility table value. The oxygen atom is very reactive and forms oxides with virtually all other elements, with the exception of helium, neon, argon and krypton. K and T = 303. 44 Note that the water content in Table 1.11 can be expressed as λ, which is defined as hydration number. Platinum(IV) bromide is the chemical compound composed of platinum and bromine with the formula PtBr4. Oxygen Gas - Specific Heat - Specific heat of Oxygen Gas - O 2 - at temperatures ranging 175 - 6000 K Salinity of Water - Salinity of fresh, brackish and sea water Solubility guidelines for ionic compounds in water - Guidelines or solubility rules to predict whether or not a given ionic compound is soluble in water at room temperature Result: 7.27 is the mg/L value that corresponds to an 80% DO Saturation reading of a sample with zero salinity at 20º C. The second variable that affects DO concentration is … Q: N/A: Only the tabulated data between T = 273. K the tabulated data could not be parameterized by equation (reference missing) very well.
