Element 53 - Iodine - Science Notes and Projects." Science Notes and Projects. Wordpress, 31 May 2013. Web. 22 Jan. 2015.
Intro to Iodine:
Iodine is a chemical element that can be found in common places such as, ocean water, soil, and air that is around the ocean. This element is crucial to the human body's health, the ocean, and science. Even though Iodine is good thing and is essential to the world, it can be toxic taken in large amounts. The human body needs it mostly to keep healthy and protect the thyroid gland from radiation. Iodine has helped scientists find ways to create medicines that would help people with things as simple as iodine deficiency to helping thyroid cancer.

The History of Iodine:

The discovery of Iodine was a complete accident. Barnard Courtois discovered Iodine in 1811 when he was extracting potassium and sodium from seaweed ash. After Courtois extracted potassium and sodium, he added sulfuric acid to help the process. He accidentally added too much sulfuric acid, which created a mass of violet gas. The gas then condensed on metal objects in the room, this causes solid iodine to form. Barnard Courtois was not trying to find a way to help mankind, but destroy it. He was trying to find a way to create gunpowder that was usually made by wood ashes, but because of the war they were out of wood ashes and had to use seaweed ash.
Iodine in Everyday Life:
Iodine is a key component in every day life. A persons body must have iodine, but the body is not able to produce it. The thyroid gland needs iodine in order to create hormones. If the thyroid lacks iodine the thyroid will have to work harder in order to create hormones. There are also other serious side affects that can happen if there is a lack of iodine in the human body such as, autoimmune disease and thyroid cancer. Scientists believe that a person can also develop endometrial, prostate, and breast cancer from a lack of iodine. To get iodine in your body you must have it in your diet. It is hard to find iodine in foods unless it has been added to your food. It is easiest to find iodine in dairy products or in the ocean, because it is condensed with sea life, especially seaweed. Iodine is found in every day foods such as, organic yogurt, strawberries, potatoes, cranberries, and sea vegetables, like kelp.

Iodine Toxicity:
Surprisingly, iodine itself is not edible. If a human were to eat elemental iodine they could possibly die. Large doses of iodine in its solid state can cause sores on the skin and large amounts of iodine in the vapor form can cause serious eye irritation. When a person eats iodine it is not just iodine. For example, iodide ion or nascent iodine are common forms of iodine that are consumable. Even consuming to much of edible forms of iodine, such as sodium iodide or potassium iodide can cause side affects due to an overdose. Having an overdose of these edible forms of iodine can cause abdominal pain, a fever, vomiting, and a lack of being able to catch your breath. People must be aware of the products they are using and should also take the correct amount of iodine.
Iodine Reactions:Iodine in general is not a highly reactive element. The most reactive thing Iodine does is become a violet color and shows small amounts of flames.
Iodine and Aluminum: together with a little bit of water they can create a violet colored gas. This reaction can also include a small amount of flames at the bottom. Sodium and Iodine: together these elements create the same reaction that iodine and aluminum do. Iodine Reaction Videos:https://www.youtube.com/watch?v=BqeWpywDuiY

The name Iodine comes from the Greek word ‘iodes’ which means violet. It is called this because when it evaporates it becomes a violet color.
2. Iodine is good in small amounts, but can be extremely harmful in large amounts 3. Large doses of iodine in its solid state can cause sores on the skin and large doses of iodine in the vapor form can cause eye irritation. |
