how to separate iodine from tincture of iodine
Answers
Read it carefully.
Explanation:
Typically Iodine is not dissolved in just plain water as it has very low water solubility (0.284 g/L). Usually a mixture of elemental Iodine and Potassium Iodide is dissolved in water as Potassium Iodide increases Iodine’s solubility through formation of Triiodide anions. You can separate the Iodine from the water and convert the potassium iodide into elemental Iodine by mixing 1 part of a 5–13% solution of Iodine/Potassium Iodide with 1 part distilled water and 1 part 3% Hydrogen Peroxide Solution followed by 1/12 part 32.45% hydrochloric (Muriatic) acid. Place this mixture in a sturdy acid resistant plastic jug with the cap on but not tight. Cover the container with a dark towel and place in a dark, cool area for 10–12 Hours. It’s very important to keep this mixture out of direct light. After 12 hours or so all of the potassium iodide will have been reduced to elemental iodine and will precipitate to the bottom of the container as dark violet to black crystals. filter and then rinse the crystals with ice cold distilled water and then wrap them up in a cloth and place them in a container and cover them with a desiccant like calcium sulfate or calcium chloride for a day or so to dry, then simply store them in an airtight container as iodine crystals will sublime into a gas if not stored properly.
