A photochemical method for determining the oxygen concentration in air-saturated non-aqueous solvents has been developed. Aceton (ook bekend onder de namen dimethylketon, DMK en propanon) is een kleurloze vloeistof die veel als oplosmiddel wordt gebruikt (onder andere nagellakverwijderaar in het dagelijks leven). Solubility is the property of a solid, liquid or gaseous chemical substance called solute to dissolve in a solid, liquid or gaseous solvent.The solubility of a substance fundamentally depends on the physical and chemical properties of the solute and solvent as well as on temperature, pressure and presence of other chemicals (including changes to the pH) of the solution.

HHS This site needs JavaScript to work properly. Because of the reduced solubility of \(O_2\) at higher temperatures (Figure \(\PageIndex{2}\)), the warmer water contains less dissolved oxygen than the water did when it entered the plant. The only information I have on Acetone is its Solubility parameter and Polarity, which may be useful if I compare acetone to a more well known solvent (Water), and scale accordingly, although I'm concerned because they're different chemical species.  |  Please enable it to take advantage of the complete set of features!
