Redox Titration Lab

The purpose of this lab was to determine the number of electrons that manganese in permanganate ion will gain in an oxidation reduction reaction with hydrogen peroxide.This lab was more difficult than the previous one, as my partner and I had to repeat the lab a few times to ensure we had done it correctly. The first time there was a chance we got the hydrogen peroxide and the hydrochloric acid mixed up, and I didn’t want to risk it. The second time we ended up forgetting a step and just got completely lost. It wasn’t that the procedures were difficult, it was more the fact we couldn’t always understand the wording of the steps and I think both of our self-confidences were low so we would think we did it wrong when it was correct. I think re-doing the lab so many times allowed us to learn more overall. The other groups were also nice enough to clarify some of the directions, which helped us complete the lab in the end. Are results were pretty close to the other groups so I believe we did this lab correctly.
