Question
The water used in this experiment is sparged with nitrogen to remove any dissolved oxygen. The proton-coupled reduction of oxygen is shown in the following half reaction: O2 + 4 H+ + 4 e- -> 2 H2O a. Explain why sparging a solution with N2 to remove dissolved oxygen is an equilibrium process. b. Using the half reaction above, write the balanced equation for the reaction of ascorbic acid with oxygen. Show your work. c. If you didn’t know whether or not O2 is capable of oxidizing ascorbic acid, how would you determine this by consulting data? What data would you consult and what would you look for?Explanation / Answer
Henry's law states: "At a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid."
So when the concentration of N2 is increased by bubbling it. Conc. Of O2 decreased.so O2 goes to the atmosphere.
Look for weight dreducrion. Because it emit H2O2
