Applications
Iodine is also used to make polarising filters for LCD displays. Iodide is added in small amounts to table salt, in order to avoid iodine deficiency affecting the thyroid gland. The radioactive isotope iodine-131 is sometimes used to treat cancerous thyroid glands.
 
Description
Iodine is a non-metallic, dark-gray/purple-black, lustrous, solid element. Iodine is the most electropositive halogen and the least reactive of the halogens even if it can still form compounds with many elements. Iodine sublime easily on heating to give a purple vapour.
 
Preparation
Iodine 0.1 N: Weigh 40 g of potassium iodide (KI) in a 500 mL glass-stoppered flask and dissolve in 100 mL of purified water. Let the solution come to room temperature, add 12.7 g of resublimed iodine (I2), restopper the flask, and swirl the flask until the iodine is completely dissolved.
 
Chemical Properties
Iodine is a non-metallic element with distinctive purple-black solid crystals, known for its sublimation, ability to form diatomic molecules (I2), and its use as a disinfectant and in thyroid hormone synthesis.
 
Definition
Iodine is a chemical element with the symbol “I” and atomic number 53, known for its distinctive purple-black color, essential role in thyroid hormone synthesis, and use as a disinfectant and in various chemical applications.
