Explanation:
add 1 mL of sulfuric acid and 3 g of potassium iodide, swirl, and let stand in the dark for 10 min. Titrate the liberated iodine with 0.1 N sodium thiosulfate volumetric solution, adding starch indicator solution near the end of the titration. One milliliter of 0.1 N thiosulfate corresponds to 0.002849 g of H5IO6.
