Iodine deficiency

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…

Introduction As humans are unable to produce Vitamin C (ascorbic acid) but still require it for proper body function, humans obtain Vitamin C from external sources.1 Historically, citrus fruits, which have a comparatively higher amount of Vitamin C, were eaten to achieve proper amounts of Vitamin C or prevent scurvy. During the age of long sea voyages, where fresh food was scarce, scurvy was prevalent and extremely detrimental .2 However, fruit was not always available or economically feasible.…

Ever feel tired and have trouble concentrating? Or lose a lot of weight, without even trying? Are these signs of aging or could it be something more serious? Many men and women suffer from a systemic disease and some may not even realize it. Hyperthyroidism disease can be overlooked and should not be taken lightly. The thyroid is a gland at the base of the neck, kind of shaped like a butterfly. This gland can alter a persons life in many ways, therefore it is important to understand what…

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…

front part of the neck. In most people, the thyroid cannot be seen or felt. It is butterfly shaped, with 2 lobes — the right lobe and the left lobe — joined by a narrow isthmus. The thyroid gland has 2 main types of cells: Follicular cells which use iodine from the blood to make thyroid hormones, which help regulate a person’s metabolism…

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.…

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 clock demonstration experiment to…

There was a stage in my life, maybe between grades 11 and 12, where I drank Med-lemon every single morning for a good year. Not because I was sick or feeling a sickness coming on, but because I did not want to get sick. My mentality was that prevention is better than cure; and my parents who love me so much and just want me to be happy would go out of their way after work and buy me a box of Med-Lemon from Clicks which would cost roughly around R70. I didn’t really even begin to consider the…

During the Foreclosure Crisis several years ago, my community was hit hard. I never thought I would see homes in my neighborhood being foreclosed. It was unbelievable. I was in middle school and high school when this was going on and heard my parents discussing this many times. I look back and think there were things that could have been done to prevent this from being a nation-wide disaster. I believe that there are things that can be done to minimize the effect of a foreclosure crisis…

taken in in small amounts. Minerals have many health benefits. A mineral deficiency exists when an individual does not take in enough of a certain mineral. This can seriously affect one 's health. Two mineral deficiencies in humans are iron and magnesium. In this paper these two mineral deficiencies will be discussed. First, the significance of mineral deficiencies will be discussed. Then, the symptoms of these deficiencies will be observed. Next, this paper will explore the benefits of…
