Iodine

Iodine is essential on the new plant and this is why. Iodine is a key component of the hormones made in the thyroid gland. These hormones are absolutely critical to human health, helping to control energy production and utilization in nearly every cell of the body. David Brownstein explains in his books “Iodine: Why You Need It, Why You Can’t Live Without It”, how iodine is crucial in a person’s life by saying “My experience has shown that iodine in doses ranging from 6-50mg/day is adequate to provide iodine for the vast majority of the population” (pg. 109) and “Chemical substances made by the thyroid gland, which is located in the front of the neck. This gland uses iodine to make thyroid hormones, which are essential for the function of every cell in the body. They help regulate growth and the rate of chemical reactions (metabolism), and are involved in the circadian rhythms that govern sleep, among other essential functions.” (pg. 256) Iodine is a crucial part for the health of human beings because it balances a healthy way of life and an active diet. On the other hand there are some things about iodine that makes it not able to make it on the new planet. Taking too much amounts of iodine can lead to…

Title: Stoichiometry to Calculate Reaction of Zinc and Iodine and Law of Conservation of Mass Authors: Sang Nguyen and Sami Biro Introduction II. Materials and Methods A. Materials Zinc (Zn), iodine (I2), acetone (C3H6O), acetic acid (C2H4O2) and zinc iodide (ZnI2) were used to conduct this experiment in order to confirm the validity of the law of conservation of mass as well as to use Stoichiometry to calculate the reaction between zinc and iodine. There are some precautions that one must…

Joseph 10/23/14 Mrs.Flannery Chemisty 10A Iodine: During the course of this project, I have learned many things about the element Iodine and it's contributions to the world. In the early 1800's, Bernard Courtois manufactured potassium nitrate and used seaweed ash as his mains source of potassium. one day in 1811, Courtois added sulfuric acid and saw purple fumes which condensed to form…

The objective of today’s lab was to determine the reaction rate of iodine and determine the reaction order for H+ and acetone. In order to do this, we ran 7 reactions with HCl, I2, Water, and Acetone. Every Run had different amounts of one of the components. These reactions allowed us to calculate the reaction rates for each of the 7 trials by dividing the molarity of the I2 by the time the reaction took. Next we had to determine the reaction order which required us to put each reaction rate,…

Iodine is a metallic grey element found in the halogen part of the periodic table. In the early 1900s, many people in the U.S. were suffering from Iodine deficiencies which caused all sorts of health complications. The decision to add iodine to salt was made to remedy these deficiencies and the problems associated with them. Salt was picked as a host for the iodine, because of its widespread use and the ease at which iodine could be added. This decision did not come without a cost and today the…

Iodine is essential for a healthy and functional thyroid. An absence of this mineral may result problems in women's, in low vitality, weight gain, coldness, depression,constipation, muscle pain, cognitive decline, heart disease, and different types of cancer. Furthermore, for unborn children, an absence of iodine mineral in their mother's diet and body can causes to weak mental capacity, cretinism, and autism. Did you realize that the World Health Organization (WHO) has announced that the United…

One such study is by restricting iodine in their overall diets to reduce the amount of iodine that could be used to create the thyroid hormones that were running rampant in the cat’s body. In a study done in in the years 2011 to 2013 a group of cats with hyperthyroidism were fed a commercially available low iodine diet for the sole purpose of treating the effects of the disease. Both a canned and dry variety of the commercial available iodine restricted diet were used in said study. This study…

Iodine clock reactions also known as Landolt Clock Reactions are one of many types of reactions in Chemistry. Clock reactions are an appealing way to show different type of chemicals having a reaction towards each other. This type of chemical reaction shows the demonstration of chemical kinetics. Iodine clock reactions were discovered by Swiss chemist Hans Heinrich Landolt in 1886. The procedure of conducting an iodine clock reaction consist of two colourless chemicals being mixed together.…

CHML 1046 General Chemistry 2 Laboratory Experiment “The Rate Law of an Iodine Clock Reaction” Objectives: To apply method of initial rates for investigation of influence of concentrations of reactants on the rate of the reaction. Determine the rate law of a particular reaction experimentally. Observe the effect of catalyst on the reaction rate. Examine the influence of temperature on the rate of this reaction. Calculate activation energy for the reaction from rate constants at two…

Causing the increase of particles that then have enough kinetic energy to react when they collide. This Landolt Iodine Clock reaction: Oxidation of Bisulphite by Iodate is to be investigated. The aim of the experiment will be to discover whether a change in heat and concentration will increase the rate of reaction. It is hypothesised that when the concentration and temperature increases it will cause the rate of reaction to speed up. Firstly, The iodine clock reaction is a classic chemical…
