DENDROLOGY

Detailed explanation-1: -Using iodine to test for the presence of starch is a common experiment. A solution of iodine (I2) and potassium iodide (KI) in water has a light orange-brown color. If it is added to a sample that contains starch, such as the bread pictured above, the color changes to a deep blue.

Detailed explanation-2: -Lugol’s iodine test is a commonly used diagnostic tool when colposcopically assessing the cervix in order to identify cervical dysplasia [10, 13, 22].

Detailed explanation-3: -It is most commonly known as an antiseptic, disinfectant and starch indicator. Lugol’s solution affects the carbohydrate molecules in the following way: iodine binds to complex carbohydrates (starch in plant organisms, glycogen in animals), staining them in the process.
