How to make 10% Lugols Iodine Video Instructions along with making your own distiller from a pressure cooker and copper tube to produce distilled water for the formula.

Hope you find this instruction video useful.

To prepare a 10%
LUGOL'S SOLUTION, the ratios of the elements change, since elemental iodine is not very soluble in water, thus, a slightly higher percentage of KI is needed.

1. Put 118 ml (4 fl. oz.) of distilled water in a dark glass container. 2. Mix 33.7 grams (1.18 oz.) of potassium iodide into the solution prepared in step one. Use a wooden or plastic spoon / spatula to stir until completely dissolved --do not use metal! Stir

Add 16.9 grams of iodine crystals to the mix, being very careful not to touch the iodine crystals--they can burn the skin. If you come into contact with the iodine crystals, wash your hands immediately with plenty of water. Stir with the wooden or plastic spoon, and cover with a non-metal cover. Let it sit for 10 hours

In the morning, stir once more or shake the solution. You now have a 10% Lugol's solution, which can be taken internally or externally. If you choose to take the solution internally, note that the concentration is approximately 25.5 mg/drop! (Assuming the drop size is such that 70 drops make up 1 teaspoon).

Note: The standard Lugols iodine concentrations don't include the potassium iodide in the percent calculation. The standard Lugol's solution of 5% means that there is 5% elemental iodine in the solution and the potassium iodide KI is not considered.

However, when you calculate the mg/drop of iodine, the iodide is taken into account. To do this, note that iodide is 0.769 times the total KI present, the ratio of atomic weights of iodine to potassium. Then, [I + KI(0.769)]/ml = the concentration of iodine.

Proof that the 10% Lugols solution described above is truly 10%:

16.9 gr/(16.9 gr + 33.7 gr + 118 ml) = 0.10 or (10 %) A similar calculation can be performed for the strong iodine tincture.

Potassium iodide renders the elementary iodine soluble in water through the formation of the triiodide (I3−) ion.

<p>Interesting I could make an Lugol solution for staining or detecting how potent it is on friendly bacteria. Then recording a ph data graph with a special filter. I would use only 0.5 ml of a sample in 100 ml bacteria culture. I have done this with cobalt salts, iron salts, etc.</p>
<p>Thanks. I may have been able to figure it out myself if it wasn't for me being low on Iodine. Iodine deficiency is supposed to lower peoples IQ :) </p><p>And yes that is the way to go. Small bottle for everyday use, and a bigger bottle for supplying the everyday bottle once in a while. This way you can prepare larger amounts as long its stored dark and cool.</p><p>The more I read about Iodine (and Potassium Iodide) the more I value my supplies of PI powder and Iodine crystals. Also reading that selenium is essential for Lugols Iodine to work properly if used for various deficiency related health problems. </p>
<p>What are the ingredients I need for this</p>
<p>Im sorry to say that your calculations are incorrect. Concentrations should be wt/vol and not wt/wt as you are using. You never even mention the final volume of the solution.</p><p>A 5% Lugols solution should contain 50g Iodine (5% wt/vol) and 100g Potassium Iodide (10% wt/vol) in a final volume of 1 litre. This will have a total Iodine content of (50 + .76 x 100) = 126 g per litre, which is equivalent to 6.25 mg per drop (1/20 ml).</p><p>Therefore for a 10% solution, the quantities above will be double (ie 100g Iodine and 200g Potassium Iodide) in a final volume of 1 litre, and 1 drop will contain 12 mg total Iodine.</p><p>I hope you havent poisoned too many people.</p><p><a rel="nofollow">[delete]</a></p>
<p>How do you get iodine?</p>
<p>Iodine I3- is very corrosive and toxic!!! However this would be less toxic dependent on the dose. I use I3- iodine for gram staining and the kit is very very expensive. </p><p>A few science companies can sell iodine but I would take pills and NOT attempt to make iodine for human consumption. Remember anything you make in a lab should not be eaten. Quite risky in my opinion. It is interesting and complex but I enjoyed it and the video. </p><p>This theory is how i will determine how iodine effects bacteria cultures.</p>
<p>Sorry, you lost me at step two where you refer to the &quot;solution prepared in step one&quot;. No solution was mixed in step one; only water was added to a bottle, and that is not a solution. What comprises the step-one &quot;solution&quot; please?</p>
<p>A potentially dangerous and highly corrosive formula at 10%. 5% is the perfect formula for human consumption and you don't have to step it down to utilize it daily. This article is misinformation. In a pinch if limited with resources 2.5% is worthy as well. </p>
<p>Confused on mg/drop. The J.Crow brand of Lugol's says: &quot;LUGOL'S 5%: Each VERTICAL drop is about 6.25 mg's of iodine/potassium iodide (2.5 mg iodine, 3.75 mg potassium iodide)&quot; and I've read that elsewhere.</p><p>If that's so, than wouldn't your 10% solution be something like 12.5 mg/drop instead of 25.5?</p>
<p>Very well explained.</p><p>Can I take half the amounts of what you used of all 3 ingredients and still get 10% Lugols Iodine?</p><p>Asking because you apparently can't store the Logols for more than a year.</p><p>Thanks, Martin</p>
Yes you can make half the amount. <br>Re iodine shelf life. If stored in a brown glass medicine bottle, it reduces effect from light, and providing it is kept cool, it will last for many years. You can also transfer some of the Lugol's to a smaller vessel to save keep opening the main bottle.
<p>Not from what I have read, perhaps another formula I haven't observed yet. Original Lugols Iodine was without acetic acid. Perhaps it was added for patent aplication? </p>
correct me if I'm wrong but isn't there acetic acid in the mix somewhere? I made some years ago and I seem to recall mixing the potassium iodide and iodine to acetic.
