(Potassium Iodide)
Potassium iodide with KI chemical formula crystallized in a cubic structure.it is a White powder with high solubility in water that can be changed in yellow in the presence of air and light oxygen. Its color variation is due to the oxidation of iodide ions to molecular iodine; therefore, this material should be kept in a dry place and away from the direct sunlight. It was first used in 1916 to treat goiter disease. In the same year, tincture iodine and iodoform were used to disinfect cuts and scratches and to observe health principles.
Cubic structure of potassium iodide
Potassium iodide has many applications in the pharmaceutical and disinfecting industries, producing potassium iodine tablets to prevent radioactive iodine absorption, drilling, lubrication and laboratory applications in iodometric titrations.
