1. Write the balanced equation of the reaction of O2 with vitamin C and determine the potential of the reaction. is the reaction spontaneous? explain.
2. suppose the water that you used had not been boiled/deoxygenated. how would this have affected the amount of thiosulfate needed in the back titration, and the amount of vitamin C that you calculated to be in the sample that you used? explain.
A sample of O2 gas was collected over water at 23ºC and 252 torr. What is the partial pressure of the O2. (The vapor pressure of water at 23ºC is 21.2 torr.)
