Iodine

patient is allergic to seafood along with other allergies and even to go as far as asking if they are allergic to iodine specifically. The reasoning for this is that seafood is high in iodine. The fact of the matter is that iodine is an essential trace element for life, with its main role being in the thyroid’s production of certain hormones, so it is impossible to be allergic to iodine. Iodine deficiency leads to hypothyroidism, whose symptoms include goiter, and mental slowing, being the…

imaging exam with contrast material has been done, the substance is absorbed by the body or excreted through the urine or feces. There are numerous kinds of contrast materials, Iodine-composed and barium-sulfate mixtures are used in x-ray and CT imaging exams. Contrast substances can have a chemical structure that contains iodine, an organically occurring chemical element. These contrast substances can be injected into veins or arteries, inside the disks or the liquid filled spaces of the…

chemical element Iodine. Although there are at least 37 different Iodine radioisotopes, only four of them are used as tracers or therapeutic agents in medicine; these are 123-I, 124-I, 125-I, and 131-I, with the latter being the most common in clinical practice. Essentially all industrial production of radioiodine isotopes involves four aforementioned radionuclides. History of radioiodine production and usage The first radioiodine was produced by Enrico Fermi in 1934. It was Iodine-128, which…

Tropical Fruits Tropical fruit is any type of fruit produced in tree that is native to the tropics. The tropics are usually as the region and area of the globe that is between the Tropic of Cancer and Tropic of Capricorn. Tropical region has unique environmental conditions and therefore creates a habitat that is usually for diverse species of fauna and flora. Many tropical fruits are mostly used and consumed by humans, and certain fruits are widely known where its demands are high. (Site) There…

In the world of biology macromolecules are the basis of all life. The four main biological macromolecules are carbohydrates, lipids, proteins and nucleic acids. Carbohydrates contain carbon, hydrogen, and oxygen, as well as provide a means for energy and cell support in plants. .( Parsi et al, 2016) They can be further categorized by the subtitles monosaccharides, disaccharides, and polysaccharides. Since monosaccharides are monomers and thus simple sugars, as monomers are added to the chain…

A: The purpose of heating the seaweed was so that it turned into ash. We did this by placing the seaweed in a tin and burning it from the Bunsen burner. This was done so we could get iodine from the seaweed to use in the experiment. This produces the iodine we need to begin the experiment. A problem that could have occurred was placing too much seaweed in the tin so it took a lot longer to burn. Also, a bit of the seaweed were popping out the tin which is a health and safety concern so we must…

This will be referred to as the corn starch solution. This starch will be added to the mixture because without a starch, no color will show up. Iodine is a strong oxidant, which reacts with both vitamin c and starch when they are in a solution. However, because Vitamin C is a strong antioxidant, the iodine reacts with it first, and once it has finished reacting with the vitamin c, it then begins to react with the starch. Next, 500 mL of water were boiled, and from this was…

1-Paper 2-gallon size Zip- Loc bag 3-Iodine beads (available from forensic supply companies) Note: Iodine crystals can be used along with a small amount of powdered vermiculite. 4-Rubber or plastic gloves are recommended 5-Safety glasses or goggles Safety Precautions Firstly,Wear safety glasses or goggles to protect our eyes from iodine vapors. Iodine is very toxic in nature , both as vapor and through excessive skin contact. Work in a well ventilated area is necessary. We must Keep all…

dessertspoonful of residue will remain. During the experiment we piled the seaweed into a tin container and placed it on top of a tri-pod which was placed over a Bunsen burner allowing the seaweed to burn and inevitably turn into ash so the extracting of iodine can begin. It is important to make sure that not too much seaweed is added at any one time as certain sizes of seaweed pops therefore it is important to ensure that the appropriate safety clothing is worn including safety goggles and lab…
