reaction should have been 2. The experimental value that I obtained has a percent error of 9.5 % when compared to the theoretical value. This difference in the number of electrons transferred could be because I wasn’t the most precise possibly when measuring the amount of gas formed inside of the eudiometer tubes. The slight inaccuracy could also be attributed to a mistake being made at the beginning of the electrolysis. When my partner and I began the electrolysis the part of the silver wire that was connected to the metal clamp was submerged under water. This allowed the O 2 gas to escape in the form of bubbles at the connection between the silver wire and metal clamp, which resulted with no gas forming in the anode eudiometer tube. After our awesome lab instructor noticed that we had made a mistake we fixed the issue and restarted the electrolysis. I don’t know if this would have an effect on the volume of each gas formed or not, but at the very least it created another opportunity to not be as precise as possibly when recording the starting volume of gas in the cathode eudiometer tube.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
