How to make lugol’s iodine?

Here is the method for making 5% Lugol’s iodine (6.25 mg/drop) in a nutshell:

  • Obtain a clean, empty 1 quart container (with lid)
  • Fill about halfway with distilled water (RO water is also okay)
  • Put in 44 grams of elemental iodine crystal (you need a scale)
  • Stir with non-metal spoon (wood is okay).
  • Put in 88 grams of potassium iodide, and stir some more.
  • Fill jar to about 80% of capacity with distilled water.
  • Let it set overnight.
  • What is the purpose of Lugol’s solution? Throughout history, Lugol solution was used to treat the gout and as a first aid in low secretion of the thyroid (hypothyroidism). During the Chernobyl disaster, it was used to disinfect water, block radioactive iodine, and to prevent of thyroid disease.

    What does the Lugol solution test for? This solution is used as an indicator test for the presence of starches in organic compounds, with which it reacts by turning a dark-blue/black. Elemental iodine solutions like Lugol’s will stain starches due to iodine’s interaction with the coil structure of the polysaccharide.

    How does Lugol’s solution detect starch? Iodine Test for Starch and Glycogen. The use of Lugol’s iodine reagent (IKI) is useful to distinguish starch and glycogen from other polysaccharides. Lugol’s iodine yields a blue-black color in the presence of starch. Glycogen reacts with Lugol’s reagent to give a brown-blue color.

    What is a Lugol solution? Lugol’s iodine, also known as aqueous iodine and strong iodine solution, is a solution of potassium iodide with iodine in water.

    What is Lugol’s iodine stain used for? Lugol’s iodine solution is used for Gram staining and can be used as an antiseptic and disinfectant for emergency disinfection of drinking water, and as a reagent for starch detection in routine laboratory and other medical tests.

    What is function of Lugol’s iodine in Gram staining? Lugol’s solution is an aqueous solution which contains iodine (I 2) and potassium iodide (KI) in a ratio of 1:2. Lugol’s iodine solution is used for Gram staining and can be used as an antiseptic and disinfectant for emergency disinfection of drinking water, and as a reagent for starch detection in routine laboratory and other medical tests.

    How does Lugol’s iodine work? LUGOL’s. This medication contains iodine and potassium iodide. It is used along with antithyroid medicines to prepare the thyroid gland for surgical removal and to treat certain overactive thyroid conditions (hyperthyroidism, thyroid storm).
