    Cobalt(II) Oxygen adduct complex Inorganic 461 lab 2-29-2012 Abstract This experiment uses Co(salen) as a model compound illustrating the uptake of oxygen in hemoglobin. SalenH2 was prepared as the intermediate‚ and reacted with hydrated cobalt to prepare Co(salen). Using Co(salen) the oxygen up-take was tested. The synthesis of SalenH2 produced 0.65 g. The percent yield of salenH2 was 116% on the filter paper and 105% after transferring salenH2 to a vial. The melting point of salenH2‚ was

    DECISIONS SERIES Oxygen Saturation A Guide to Laboratory Assessment BY SHANNON HAYMOND‚ PHD uman life depends on the oxygen transport by hemoglobin. In healthy patients‚ the majority of molecular oxygen (O2) is bound to hemoglobin and only a small fraction is dissolved in blood. But in patients with respiratory problems or certain metabolic and genetic disorders‚ the fraction of oxygenated hemoglobin can fall to dangerously low values. Therefore‚ laboratory assessment of oxygen saturation (SO2)—the

    oxidation reduction of cobalt (II) chloride hexahydrate (CoCl­2­·6H2O) and a reaction of the product with ammonium chloride (NH4Cl) and ammonia (NH3). Through iodometric and spectrophotometric analysis‚ the percent cobalt was then found in the samples of pentaaminechloridocobalt. When looking at the iodometric analysis‚ there was a mean amount of 26.29% cobalt with an average deviation of ± 1.00%. When looking at the spectrophotometric analysis‚ there was a mean amount of 15.30% cobalt with an average deviation

    Oxygen – Carbon dioxide Cycle The Carbon Dioxide- Oxygen Cycle relates to the relationship between Carbon Dioxide [CO2] breathing plants and Oxygen [O2] breathing life forms. All oxygen-breathing life forms take in Oxygen and exhale CO2. Plants take in the CO2 and use it in their photosynthesis process and in turn give off oxygen. The Carbon Dioxide-Oxygen Cycle is a continuously occurring process whereby animals inhale Oxygen and then exhale carbon dioxide‚ and plants use the CO2 and "exhale"
