What is the other name of iodine?

For other uses, see Iodine (disambiguation). orthorhombic Iodine is a chemical element with the symbol I and atomic number 53. The heaviest of the stable halogens, it exists as a semi-lustrous, non-metallic solid at standard conditions that melts to form a deep violet liquid at 114 degrees Celsius, and boils to a violet gas at 184 degrees Celsius.

Is iodide a salt or an element?

Iodine rarely occurs as the element, but rather as a salt; for this reason, it is referred to as iodide and not iodine. Iodide is quickly and almost completely absorbed in the stomach and duodenum.

What is the importance of iodine numbers in organic chemistry?

Iodine numbers are often used to determine the amount 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.

What is the role of iodine in the body?

The higher recommended daily allowance levels of iodine seem necessary for optimal function of a number of body systems, including lactation, gastric mucosa, salivary glands, brain cells, choroid plexus, thymus, and arterial walls.

Iodide is the salt, which could for example, be iodine combined with calcium or potassium, and can be found in seaweed sources and mineral deposits. What is IODIDE? Iodide is the ion form of iodine, occurring when iodine bonds with another element, such as potassium.

What is an ionic compound of iodine called?

It is a mixture, mostly the compound sodium chloride (NaCl, salt) and a tiny amount of potassium iodide, which supplies a dietary need for iodine, specifically in the thyroid gland. Is iodized salt a base or an acid?

What is the iodine number?

Iodine value. Iodine value, also called Iodine Number, in analytical chemistry, measure of the degree of unsaturation of an oil, fat, or wax; the amount of iodine, in grams, that is taken up by 100 grams of the oil, fat, or wax.

What is the significance of the iodine number in fatty acids?

Iodine numbers directly indicate the level of unsaturation in oils. The double bonds that are a major source of unsaturation react with iodine to form complex compounds. The more C C bonds present in the fatty acids, the greater the value of the iodine number.

What is the iodine value of a fuel?

The iodine value is the amount of iodine (in grams) that is consumed by 100 mL/100 grams of a fuel/substance. Iodine numbers directly indicate the level of unsaturation in oils. The double bonds that are a major source of unsaturation react with iodine to form complex compounds.

What is the role of iodine in unsaturation in fats?

Iodine numbers are often used to determine the amount 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.
