This method starts with a solution of hydrogen peroxide and sulfuric acid. To this a solution containing potassium iodide, sodium thiosulfate, and starch is added. There are two reactions occurring simultaneously in the solution. In the first, slow reaction, iodine is produced: H2O2 + 2 I + 2 H → I2 + 2 H2O WebSandmeyer Reaction 60 Molecular nitrogen is produced as the final substitution reaction proceeds. This is evidenced by formation of bubbles. The reaction is fairly complex because none of the actual reactants is stable. Three different reactants need to be made “in situ” (“in the site”, or “in the pot”), rather than being

WebIodine is well-known for the iodo-starch reaction under which a blue color develops and, as a nutrient, contained in various seaweeds. Since iodine is an element, it can not be obtained through a chemical synthesis and there being no other way to produce it than to extract from the natural resources containing it, we can say that iodine is valuable material.
