(Use three significant figures.)
If one had weighed out precisely 0.500 g of KIO3 for the primary standard solution and
dissolved it in enough deionized water to make a 250 mL solution, the molarity of that
solution would be 0.00935 M. Enter your calculated molarity of the primary standard
KIO3 solution. Use three significant figures
Standardization of the sodium thiosulfate solution using the potassium iodate
primary standard solution. We must examine each of the three acceptable trials. First,
let's consider the analyte volume. You were instructed to pipet two 10.00 mL aliquots of
potassium iodate into an Erlenmeyer flask for each analyte sample to be titrated.
Therefore, your analyte volumes of the potassium iodate should be 20.00 mL. For each
trial, enter the precise volume in mL of potassium iodate solution used in the
standardization of sodium thiosulfate (e.g. 20.00 mL or 10.00 mL).
