1. In the aeration of wastewater, liquid-gas contact systems are designed to raise the concentration toward equilibrium levels. This goal is accomplished by dispersing air bubbles into the water. An aqueous solution, initially containing 2x10 kg O2/100kg H2O is brought into contact with a large volume of ordinary air at 293°K and a total pressure of 1.013 x 10³ (you can assume ordinary air contains 21 mole % O₂). At 293ºK Henry's law constant for the oxygen-water system equals 4.06 x 10' Pa/mol fraction of oxygen in the liquid. Will the solution gain or lose oxygen? (do not just say yes or no- support your answer with a. b. MW H20=18 MW O₂-32 calculations) What will be the concentration of oxygen in the final equilibrium solution in kg O2 per 100 kg H₂O?
