Question

Vancouver Community College University Transfer Chemistry 1121 Lab #3 Redox Titration: Pre Lab Calculation Here are some practice calculations to ensure that you are doing the analysis portion of the lab correctly. The lab was completed as per the lab manual. Two standardization titrations were performed. In one, 0.5146 g of FeA.S. was titrated with 24.78 mL of permanganate solution. In the second titration, 0.4972 g of FeA.S. was titrated with 23.55 mL of solution. Calculate the mL titrant/g FeAS and determine if the two titrations have the required precision. Next, determine the concentration of permanganate solution and finally the % purity of the unknown sample if 1.8573 g of unknown was dissolved in 250.0 mL of H2O and then 50.00 mL was titrated with 14.58 mL of the standardized permanganate solution. Answers: 48.15 mL/g and 47.36 mL/g. No, the two titrations have the required precision, they do not agree within 0.5 mL/g. Permanganate solution = 0.01068 M, unknown is 59.55 anhydrous FeAS.
