A graduate student made some mistakes in water sampling because he lacks experience. After the onsite measurement showed that temperature is 25 °C and pH = 7.8, the water sample bottle was put on a cart and brought back to the lab exposed to sunshine. The pH went up to 10.2 and in the headspace of the bottle, PO2 was found to be 0.4 atm. The temperature is still 25 °C. What caused the increase in pH and Po2? What's the difference between the pE measured in lab and onsite? (We know that for equation 1/402 + H+ + e − > 1/2H2O, PE 0 = 20.8)
