Iodine is the fourth halogen, being a member of group 17 in the periodic table, below fluorine, chlorine, and bromine; since astatine and tennessine are radioactive, iodine is the heaviest stable halogen. Iodine has an electron configuration of [Kr]5s 2 4d 10 5p 5, with the seven electrons in the fifth and outermost shell being its valence ...
One study concluded the range of total body iodine content in males was 12.1 mg to 25.3 mg, with a mean of 14.6 mg. [77] It is presumed that once thyroid-stimulating hormone is suppressed, the body simply eliminates excess iodine, and as a result, long-term supplementation with high doses of iodine has no additional effect once the body is ...
Iodine numbers are often used to determine the degree of unsaturation in fats, oils and waxes. In fatty acids, unsaturation occurs mainly as double bonds which are very reactive towards halogens, the iodine in this case. Thus, the higher the iodine value, the more unsaturations are present in the fat. [1]
Iodine trichloride, which exists in the solid state as the planar dimer I 2 Cl 6, is a bright yellow solid, synthesised by reacting iodine with liquid chlorine at −80 °C; caution is necessary during purification because it easily dissociates to iodine monochloride and chlorine and hence can act as a strong chlorinating agent.
Tincture of iodine; Tincture of opium Camphorated tincture of opium ; Tincture of pennyroyal; Warburg's tincture ("Tinctura Antiperiodica" or "Antiperiodic Tincture", a 19th-century antipyretic) Examples of spirits include: Spirit of ammonia (spirits of hartshorn) Spirit of camphor; Spirit of ether, a solution of diethyl ether in alcohol
Iodine deficiency is a lack of the trace element iodine, an essential nutrient in the diet. It may result in metabolic problems such as goiter , sometimes as an endemic goiter as well as congenital iodine deficiency syndrome due to untreated congenital hypothyroidism , which results in developmental delays and other health problems.
Povidone-iodine is a chemical complex of povidone, hydrogen iodide, and elemental iodine. [4] The recommended strength solution contains 10% Povidone, with total iodine species equaling 10,000 ppm or 1% total titratable iodine. [4] It works by releasing iodine which results in the death of a range of microorganisms. [1]
Iodine is a micronutrient and dietary mineral that is naturally present in the food supply in some regions, especially near sea coasts but is generally quite rare in the Earth's crust since iodine is a so-called heavy element, and abundance of chemical elements generally declines with greater atomic mass.
