RE: mg of iodine in a drop of Lugol's

[Guest guest]

This report states it has 8.3 mg iodide per drop. http://www.thyroidmanager.org/Chapter11/11_iodine.htm This report states it has 2 mg of iodide per drop. http://www.megaheart.com/Leaflet_14html.htm But, the actual bottle itself that I have doesn't have the iodine content. Does anybody's bottle have the iodine content of one drop? Love, PamelaSkipper Beers <lsb149@...> wrote: For those interested, if my calculations are correct, the 130 mg/ml woud means one ounce contains 3846.154 mg of iodine. One teaspoon contains 641 mg of iodine. I use it by the drop, I don't know how many drops are in a teaspoon. I'll have to investigate that a little further. Skipper __

Here is a paper from the files, where we summarized what we had learned about how much iodine is in Lugol's.

HOW MUCH IODINE IS IN LUGOL’S?

· 100 gm of Lugol’s 5% Solution = 5 gm Iodine + 10 gm Potassium Iodide (KI) + 85 gm Distilled Water

· Two drops of Lugol’s = [approximately] 12.5 mg Iodine/Iodide

Explanation

· 10 gm Potassium Iodide = [approximately] 7.5 gm Iodide + 2.5 gm Potassium [For details, see below, “How much Iodide is in 10 grams of Potassium Iodide?”]

· 5 gm Iodine + 7.5 gm Iodide [from the Potassium Iodide] = 12.5 gm Iodine/Iodide

o 12.5 gm Iodine/Iodide = 12,500 mg Iodine/Iodide

§ 1 gm (gram) = 1000 mg (milligrams)

§ 12.5 gm = 12,500 mg [multiply by 1000]

· 100 gm Lugol’s = 12,500 mg Iodine/Iodide

· 1 gm Lugol’s = 125 mg Iodine/Iodide [divide by 100]

o 1 gm = [approximately] 1 ml

o 1 ml Lugol’s = 125 mg Iodine/Iodide

· Two drops of Lugol’s = 12.5 mg Iodine/Iodide

o 20 drops of an aqueous solution = [approximately] 1 ml

o 2 drops = 2/20 ml = 1/10 ml

o 1/10 x 125 mg = 12.5 mg

How much Iodide is in 10 grams of Potassium Iodide?

To determine how much iodide is in Potassium Iodide, you find the atomic weights for each on the periodic chart. Then add them together to determine the total weight. You then figure out how much of the total weight that Iodine accounts for.

Atomic Weight of Potassium (K) = 39.1

Atomic Weight of Iodine (I) = 126.9

Total Atomic Weight KI = 166.0

Iodide in 10 gm KI = 126.9/166 x 10 = 0.76 x 10 = 7.6 gm Iodide.

For simplicity, this is rounded down to 7.5 gm Iodide.

I = Iodine

I(-) = Iodide = Iodine with an extra electron, resulting in a negative charge.

Since the electron weighs almost nothing, both Iodine and Iodide have an atomic weight of 126.9.

KI = Potassium Iodide
