Prepare 100 mL of 0.0100 M KIO3. The dilute 0.0100 M KIO3 solution will be used to standardize the NazS203 titrant, so it must be prepared accurately. Although we could prepare it directly from the solid, small volumes of low-concentration solutions are best prepared by dilution of a more concentrated solution, rather than by weighing and dissolving a solid. This is because the small amount of solid needed to prepare a small volume of a dilute solution can't be weighed as accurately as a larger quantity of solid, even using an analytical balance. Therefore, you will prepare your 0.0100 M KIO3 solution by dilution of your 0.200 M KIO3 solution. Using a volumetric pipette, prepare the solution in a 100-mL volumetric flask. Calculate the exact molarity of the solution you have just prepared, again using the dilution formula, this time with the exact molarity of the 0.200 M KIO3 solution prepared above. Show your calculation and report your result with as many significant figures as are justified. Label your solution with the identity of the solution, its exact molarity, your name, and the date.

How do you solve for the exact molarity of KIO3 solution?

Prepare 100 mL of 0.0100 M KIO3. The dilute 0.0100 M KIO3 solution will be used to standardize the NazS203 titrant, so it must be prepared accurately. Although we could prepare it directly from the solid, small volumes of low-concentration solutions are best prepared by dilution of a more concentrated solution, rather than by weighing and dissolving a solid. This is because the small amount of solid needed to prepare a small volume of a dilute solution can't be weighed as accurately as a larger quantity of solid, even using an analytical balance. Therefore, you will prepare your 0.0100 M KIO3 solution by dilution of your 0.200 C. M KIO3 solution. Using a volumetric pipette, prepare the solution in a 100-mL volumetric flask. Calculate the exact molarity of the solution you have just prepared, again using the dilution formula, this time with the exact molarity of the 0.200 M KIO3 solution prepared above. Show your calculation and report your result with as many significant figures as are justified. Label your solution with the identity of the solution, its exact molarity, your name, and the date. sml Volume of 0.200 M KIO3 needed 154
