    USP Strong Iodine Tincture is defined in the NF as containing in each 100 mL, 6.8 to 7.5 gram of iodine, and 4.7 to 5.5 gram of potassium iodide. Purified water is 50 mL and the balance is alcohol. This 7% tincture solution is about 3.5 times more concentrated than USP 2% tincture. [citation needed]

    en.wikipedia.org/wiki/Iodine_clock_reaction

    Sodium thiosulfate is used to reduce iodine back to iodide before the iodine can complex with the starch to form the characteristic blue-black color. Iodine is generated: 2 I − + S 2 O 2− 8 → I 2 + 2 SO 2− 4. And is then removed: I 2 + 2 S 2 O 2− 3 → 2 I − + S 4 O 2− 6. Once all the thiosulfate is consumed the iodine may form a ...

    The iodine content and thus the active chlorine content can be determined with iodometry. [ 3 ] The determination of arsenic(V) compounds is the reverse of the standardization of iodine solution with sodium arsenite , where a known and excess amount of iodide is added to the sample:

    The iodide anion is a good nucleophile and will displace chloride, tosylate, bromide and other leaving groups, as in the Finkelstein reaction. Alcohols can be converted to the corresponding iodides using phosphorus triiodide. Illustrative is the conversion of methanol to iodomethane: [15] PI 3 + 3 CH 3 OH → 3 CH 3 I + "H 3 PO 3 "
