碘顆粒在水中溶解度最高只能達到1g/3000mL，約是0.03%。然而若以碘化鉀或碘化鈉水溶液為溶劑，溶解度會因形成碘鹽複合體而大幅增加。例如 Iodine Topical Solution, USP即利用此反應配製，含有2%碘及2.4%碘化鈉。

原文：

For example, iodine granules are soluble in water only to the extent of 1 g in about 3,000 mL. Using only these two agents, the maximum concentration possible would be approximately 0.03% of iodine. However, through the use of an aqueous solution of potassium iodide or sodium iodide as the solvent, much larger amounts of iodine may be dissolved as the result of the formation of...

However, through the use of an aqueous solution of potassium iodide or sodium iodide as the solvent, much larger amounts of iodine may be dissolved as the result of the formation of a water-soluble complex with the iodide salt. This reaction is taken advantage of, for example, in Iodine Topical Solution, USP, prepared to contain about 2% iodine and 2.4% sodium iodide.
