Potassium Iodide 10% represents an indispensable laboratory chemical used primarily in medical and histological diagnostics. This reagent has many uses, including application in iodine-starch reactions to identify starch in biological samples. During the reaction, an intense blue-black color product is formed, indicating the presence of starch. Furthermore, potassium iodide is commonly used in iodometric titration methods in which iodine is released and then titrated. These applications allow qualitative and quantitative analyses of various substances, opening up a wide range of diagnostic possibilities. Ultimately, the strength of Potassium Iodide 10% lies in ensuring accurate and repeatable results, which are essential for validating scientific results in a wide variety of medical and histological contexts.
