Unformatted text preview: measured average weight percent of C 2 O 4 , the number of waters of hydration was 2.703, whereas the true value for waters of hydration was 2. After calculation of RSD and REA, which were 1.927% and 4.551% respectively, it was clear that the measured data was more precise than accurate. However, neither of the values showed an extreme deviation between the measured values and the true values. Based on this closeness, the analyte seems to be fairly pure. The main sources of error in this lab could be attributed to reading errors of the volume on the buret, and the difficulty in determining the exact end point. The end point may have been slightly overshot, resulting in a smaller molarity of KMnO 4 . 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Name Liz Zharovsky Bench C19 Lab day and section Tuesday - 2 TA Ramyaa Mathialagan Partner N/A Title: Oxidation-reduction titration...
