Iodine

of two atoms of the same element. These are: hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine and iodine. For example, when we refer to iodine, in a chemical reaction, we write it down as I2, which is a diatomic molecule. The table below shows the elements and their diatomic molecule: Element Diatomic Molecule Hydrogen H2 Nitrogen N2 Oxygen O2 Fluorine F2 Chlorine Cl2 Bromine Br2 Iodine…

solution in the dialysis tube turned bluish black in color due to the transfer of iodine from the beaker to the bag which contains starch and glucose . The solution in the beaker turned brown after Benedict’s test ( table 1) . This indicates that the dialysis tubing was permeable to both glucose and iodine but not starch ( work helper, 2017) . Starch didn't pass because the solution in the beaker which contains iodine didn’t turn blue-black in color but remained yellow, this means that the…

As the temperature increases the reaction the amylase is undergoing increases therefore the different amylases used in the classroom broke down to maltose. One of element we used was the iodine test as the temperature increase the color in the iodine decreased. As a result starch was catalyst by using the iodine test in which the color help indicate…

According to official website for Gatorade, Gatorade is the one of the most famous sports drinks, which was formulated in early summer of 1965 at the University of Florida College of Medicine to help football players to facilitate proper hydration. A private company obtained patent to sell the drink publically and started adding chemicals to processed Gatorade in 1969 (Newsmax Health, 2013). Soon after, Gatorade spread out athletic fields and it became the official sports drink of the NFL in…

Purpose: The purpose of this experiment is to determine the type of chemicals that are inside the mislabeled bottles. Materials: • pH strips • 8 bottles of known chemicals: o silver nitrate o iron (III) nitrate o copper (II) nitrate o sodium iodine o sodium hydroxide o nitric acid o lead (II) nitrate o sodium carbonate • 8 bottles of unlabeled chemicals the same contents as known chemicals • 1 well tray Procedure 1. Place 7-10 drops of each chemical (known and unknown) into separate wells…

The remaining iodine when titrated gives a blue color with starch indicator. The volume of titrant used is proportional to the sulfite concentration In this protocol, iodide ion is generated by the following slow reaction between the iodate and bisulfite: IO3− + 3 HSO3−…

thoroughly and dry them completely. After you have done this, make sure there are no clothes or other objects obstructing the area of sterilization. There are two different methods of sterilization depending on the medium of sterilizer that you use. If iodine was the medium that was chosen, the procedure takes slightly longer than if alcohol was used. Referring back to the article from the Safe Care Campaign, it says to “apply perioperative antiseptic skin preparation in concentric, enlarging…

The elimination of the alpha proton causes the alpha carbon to be nucleophilic and allows it to attack iodine molecule. The presence of the iodine in the alpha carbon makes the two other hydrogens more acidic, therefore the two hydrogens get attacked by the nucleophilic base until all of them are replaced by the iodine. Then, the bond between carbonyl carbon and the carbon containing the iodine molecules will break and form an acid salt and iodoform which is a yellow precipitate (Razote, et al.,…

The thyroid gland is an organ in the endocrine system located in the throat next to the Adam’s apple and although small shaped is extremely important to a patient’s health. The primary function of the thyroid is to produce two specific thyroid hormones, triiodothyronine (T3) and thyroxine (T4), and secrete calcitonin that circulates continuously from the gland through the blood to all parts of the body. In fact, thyroid hormones are essential for operating “almost all the cells in the body,…

I.) Introduction The worst feeling for a parent is seeing their child in pain. I discovered this when I was having dinner with a family friend, Ryan, and he told me about when his daughter, Brooke, had a severe allergic reaction to shrimp. He told me about how his family was having a Fourth of July barbecue one year and everything seemed normal. Brooke had just gotten a plate of food, on which was a shrimp kabob. She started eating and after a minute or two, she started wheezing. The…
