(a) Potassium iodate solution was prepared by dissolving 1.022 g of KIO3 (FM 214.00) in a 500 mL volumetric flask. Then 50.00 mL of the solution was pipetted into a flask and treated with excess KI (2 g) and acid (10 mL of 0.5 M H2SO4). How many millimoles of I3− are created by the reaction? (b) The triiodide from part (a) reacted with 37.54 mL of Na2S2O3 solution. What is the concentration of the Na2S2O3 solution? (c) A 1.223...

1. In the second step she prepared the vinegar solution for the titration in the following manner 25.0 mL of vinegar were diluted to 250.0 mL in a volumetric flask, and 25.0 mL of this diluted solu- tion required 8.27 mL of the above standardized NaOH (gquestion 5a) to reach the phenolphthalein endpoint. What is the molarity of the acid as it was titrated (diluted vinegar)? a. Use the dilution equation to determine the molarity of the acid prior to...

Using the volumes of NBS solution you just entered and the average molarity of the NBS standard solution, calculate the milligrams of ascorbic acid in the 10.00 mL Vitamin C sample for each trial. Enter your calculated milligrams of ascorbic acid in the 10.00 mL Vitamin C sample, for each trial. Be sure to enter your calculated milligrams in the corresponding order that you entered your NBS volumes previously. The NBS volume you entered for entry #1 previously should correspond...
