Description of Potassium iodide

Potassium iodide is an inorganic compound with the chemical formula KI. This white salt is the most commercially significant iodide compound, with approximately 37,000 tons produced in 1985. It is less hygroscopic (absorbs water less readily) than sodium iodide, making it easier to work with. Potassium iodide occurs naturally in kelp. Kelp’s iodide content can range from 89 µg/g to 8165µg/g.
Aged and impure samples are yellow because of the slow oxidation of the salt to potassium carbonate and elemental iodine.
Potassium iodide is medicinally used for thyroid blockade, thyroid storm and also as an expectorant. It is on the WHO Model List of Essential Medicines, the most important medications needed in a basic health system.

What is Potassium iodide?

     With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Potassium iodide which has developed particularly rapidly in recent years. Do you know about Potassium iodide?

The official answer: Potassium iodide is an ionic compound in which iodine ions can form a dark yellow precipitate of silver iodide with silver ions (decomposed by light and used to make high-speed photographic films), so silver nitrate can be used to test for the presence of iodine ions. Iodine, as a component of thyroxine, is closely related to the basal metabolism of livestock and is involved in almost all material metabolic processes. Iodine deficiency in livestock can cause hyperplasia and hypertrophy of the thyroid gland and a decrease in the basal metabolic rate, which affects growth and development. Iodine needs to be added to the feed of young animals and livestock in iodine-deficient areas, and to the feed of high-yielding dairy cows and high-yielding egg-laying hens, where the need for iodine increases.

What’s the application of Potassium iodide?

As a component of thyroxine, iodine is involved in the metabolism of all substances in livestock and poultry, and is an essential hormone for livestock growth, reproduction and lactation. It can improve the growth performance of livestock and poultry and promote the health of the body. If the livestock body is deficient in iodine, it will lead to metabolic disorders, disorders in the body, goiter, affect the nerve function and the digestion and absorption of fur and feed, and eventually lead to slow growth and development.
