The solubility of oxygen in water at 25 degrees celsius is

Water and Pentanol Water and pentanol have a lower solubility than expected. Why? Although both solvents have polar groups attached, the proximity and strength of the hydrogen bonds between water molecules will be much greater than when pentanol is in the mix with its long non-polar hydrocarbon tail interrupting the hydrogen bonding of the water molecules surrounding it. Dec 28, 2013 · Solubility decreases as temperature increases. Assuming normal atmospheric pressure and composition, water at 0˚C can hold a maximum of ~15ppm DO, while water at 50˚C can only hold ~5ppm. Once the water reaches 100˚C, solubility is zero. Therefore, if you've brought water even close to a boil, you've removed virtually all the DO. The quantity of oxygen that can dissolve in water depends on the temperature of the water. (So thermal pollution influences the oxygen content of water.) The graph shows how oxygen solubility $ S $ varies as a function of the water temperature $ T $. (a) What is the meaning of the derivative $ S'(T) $? What are its units?
