An 8% Solution of iodine and potassium iodide in distilled water.

A History of Lugol's Iodine

Jean Francois Coindet (1774-1834) was the first to use iodine for medicinal use. Lugol’s was first made by French physician J G A Lugol in 1829. Dr Lugol researched substances that could help treat infections and found that iodine could be used and showed promise in this field. He used the 1:2 ratio of iodine to potassium iodide that is still used today.


What is in this solution?

32g of iodine and 64g of potassium iodide is added to distilled water to make 1 litre. This means that there is 1.6mg of iodine and 2.4mg of iodide in 1/20ml (1 metric drop).

According to Wikipedia a "5% solution consists of 5% (wt/v) iodine (I2) and 10% (wt/v) potassium iodide (KI) mixed in distilled water." However, we believe that the convention for naming Lugol’s solution this way is misleading. Potassium iodide also contains iodine. In fact, 76% of the weight of each KI molecule is the iodine atom. Therefore, in order to understand the full amount of iodine in a solution, add the amount of pure iodine (I2) PLUS 0.76 of the weight of potassium iodide.
