Free Response - 2 points. In the box provided, discuss the relative accuracy of measurements made with a pipet and with a buret. Generally, a pipet is more accurate than a buret. Do your experimental results support this statement? Explain why the pipet should be more accurate than a buret. What procedural differences between recommended practice and student usage do you think would result in a student's data not supporting this statement? It is true that in general, a pipet is more accurate than a buret. However, based on my experimental results, using the pipet gave a higher relative error of 0.702% than using a buret which gave a 0.5115% relative error. In my case, the pipet was most likely not cleaned thoroughly enough. The pipet should be more accurate than a buret because not only did the procedure stated to use the pipet to measure exactly 10 mL, the pipet was designed to measure exactly 10 mL. With the buret however, the procedure stated that we should approximate 24 mL, which would inevitable lead a more imprecise result than a pipet. If a
