dc.description.abstractIodine is a useful topical antiseptic due in part to its ability to dissolve in both hydrophobic and hydrophilic media. It has broad spectrum antimicrobial activity and its ability to readily pass through cell membranes plays an important role. Iodine is also a useful catalyst in carbohydrate chemistry for a range of transformations. Using it in such a capacity certainly makes traditional synthetic chemistry more colorful, as solutions of iodine are intensely colored, ranging from blue to violet to deep red depending on the solvent and other solutes. Iodine can be readily converted to colorless iodide solutions by the addition of sodium thiosulfate or sodium metabisulfite. Because iodine can pass between an organic/aqueous interface (Figure 1), this property offers an obvious visual demonstration of membrane permeability that is related to the distribution of molecules in living organisms. This simple protocol can be carried out using readily available household chemicals.en_US
