The body also needs thyroid hormones for proper bone and brain development during pregnancy and infancy. Master the topic with expert guidance at Vedantu. Iodine occurs in the environment and in the diet primarily as iodide. Many saltwater and plant-based foods contain iodine, and this mineral is most widely Iodine is a mineral found in some foods. We would like to show you a description here but the site won’t allow us. Iodides include salts such as sodium iodide and organic compounds such as methyl iodide. Iodide does not react with starch; nor do solutions of iodine in nonpolar solvents. Worldwide, iodine deficiency affects two billion people and is the leading preventable cause of intellectual disability. Understand iodide (I⁻), its structure, properties, and key uses in chemistry. The nucleophilic substitution reaction can be represented as Buy HI4011 Solid State Iodide Half-Cell Ion-Selective Electrode for accurate iodide measurement, 0. In solution, it appears yellow in low concentrations, and brown at higher concentrations. It tends to accept an electron and exists as a negatively charged ion. In part because of its size, iodine forms relatively weak bonds with most elements ChemSpider record containing structure, synonyms, properties, vendors and database links for Iodide ion, 20461-54-5, Iodide, XMBWDFGMSWQBCA-UHFFFAOYSA-M The triiodide ion is the simplest polyiodide; several higher polyiodides exist. In a second reaction, thiosulfate ions react with the iodine produced in the main reaction to form iodide ions again. Iodine is needed so that your thyroid gland can function properly. Its classic BNC connector ensures compatibility with most standard laboratory instruments. It gains the electron that's why it has a negative charge Iodide ion. The following diagram illustrates the key steps of iodide uptake and organification within a thyroid follicular cell. Although the iodide ion is colorless, iodide solutions may acquire a brownish tint as a result of oxidation of iodide to free iodine by atmospheric oxygen. Triiodide ion I2+ I-➡I3- Three center, four electron bonding [I-I-I]- Lewis Structure I- Chemical substance consisting of iodine combined with another element. Additionally, in comparison, the lighter halides are considerably much smaller: chl What is Iodide? Iodide is an anion with a valency of -1. Iodine reduces thyroid hormone and can kill fungus, bacteria, and other microorganisms such as Mar 14, 2019 · It’s important to get enough iodine in your diet. Iodides are compounds containing the iodine anion, I-. It regulates hormones, fetal development, and more. In the main reaction, hydrogen peroxide reacts with iodide ions to produce iodine molecules. The triiodide ion is responsible for the well-known blue-black color which arises when iodine solutions interact with starch. This is attributed to the lower basicity of the iodide ion and the weaker carbon-iodine bond compared to the carbon-chlorine bond. The meaning of IODIDE is a salt of hydriodic acid; also : the monovalent anion I— of such a salt. Iodide is given as the largest monatomic anion, and it is assigned with a radius of around 206 picometers. In everyday life, iodide is most commonly encountered as a component of iodized salt, which many governments mandate. Shop EnvMart. What is Iodide? Iodide is an anion with a valency of -1. Learn about the properties, sources, and functions of iodide ion, a halogen and an essential nutrient for thyroid hormone synthesis. When heated, methyl iodide can undergo a nucleophilic substitution reaction where the hydroxide ion (OH⁻) from sodium hydroxide acts as a nucleophile. Iodides are common in everyday life; for example potassium iodide is the iodine component of iodized salt and silver iodide is a photoactive component of silver-based photographic film. Found in foods like fish, dairy, and iodized salt, it helps produce thyroid hormones, which regulate metabolism, growth, and development. Dec 12, 2025 · The iodide ion is a strong reducing agent; that is, it readily gives up one electron. [3] Iodide Ion | I- | CID 30165 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. Iodide is often used in medicine, particularly as a supplement to support thyroid function. Dec 21, 2023 · But iodide has a negative charge. Physical Properties Of Iodide Iodide molecular weight is 126. [2] Compounds with iodine in formal oxidation state −1 are called iodides. 13 g/cm3 Iodide ion I B forms hydrophobic interactions with the side chains of Met298 and Val14, while packing off the amide of Pro13-Val14. Most environmental iodine occurs in seawater; a small amount enters the atmosphere and, through rain, enters ground water and soil near the sea. Aug 1, 2025 · For patients who are unable to get enough iodine in their regular diet or who have a need for more iodine, sodium iodide may be necessary.
