Question 7 A student performed three DCM layer titrations in Part 2 and they reported the following measurements: Determination #1 Determination #2 Determination #3 Final Burette 31.12 mL 38.12 mL 45.00 mL Reading Initial Burette 24.21 mL 31.12 mL 38.12 mL Reading Volume of DCM 6.91 mL 7.00 mL 6.88 mL Aliquot Final Burette 31.52 mL 35.64 mL 44.99 mL Reading Initial Burette 2.43 mL 9.39 mL 19.31 mL Reading Volume of Sodium Thiosulfate 29.09 mL 26.25 mL 25.68 mL Which determinations were the student's 'best two'? Calculate the percent difference for the 'best two' and show the complete calculation. Note that the concentration of standard sodium thiosulfate, which the student used, is unknown.
