The solubility of oxygen in pure water decreases in non-uniformly from 14mg/litre at 0oC to 0 mg/litre at 100oC. At 20oC its solubility is approximately 8.8mg/litre.
Water is a bent, polar compound and possesses the ability to Hydrogen bond. As a result, it has unique solubility characteristics as a solvent and functions differently at different temperatures.
The reason that it effects the solubulity of oxygen is that it is gaseous while NaCl is solid at room temperature. The oxygen molecules are effected by the increase in pressure in the way that there...
