Iodine deficiency

Reggie 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…

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,…

The optimized PF0 encapsulated hybrid NCs formulation was achieved by a two-step process (Fig 1) using nanoprecipitation and subsequently coating with chitosan. In Step-I, the nanoprecipitation technique was used to prepare PF0 loaded BSA NCs (PF0-ANC). In this nanoprecipitation technique, acetone was used as a desolvent [40]. Varying concentrations of PF0 solutions (125µM - 375µM) and BSA solution (156.25µM – 468.75µM) (Table 1) were mixed in a glass vial. The PF0 BSA solution was then added…

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…

After using a search engine, I researched the differences between Hypothyroidism and Hyperthyroidism. Although, many people might confuse the terms due to their similarities in their spellings. There are many differences between them but the main difference, in my opinion, is the change in the production of the gland activity, Underactive vs Overactive Thyroid glands respectively. Hypothyroidism is an underactive thyroid gland. This means that the thyroid gland doesn’t produce enough thyroid…

Understanding the Pathophysiology, Laboratory, Diagnostic testing and Nursing Interventions for Graves’ Disease According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) (2012), “Graves’ disease, also known as toxic goiter, is the most common cause of hyperthyroidism in the United States”. Hyperthyroidism is a disorder that occurs when the thyroid gland makes more thyroid stimulating hormone (TSH) than the body needs. The thyroid gland helps control how the body…

Biochemical tests are used to detect the presence of different kinds of organic molecules, carbohydrates, lipids, nucleic acids, and proteins. These tests include the Benedict’s Test, Iodine Test, Sudan III Stain Test, Biuret Test and many others. With these tests, the nutrients from an unknown solutions can be identified in the solution. The Benedict’s test is used for identifying reducing sugars, which are simple sugars that include monosaccharides and some disaccharides. The Benedict’s…

The difference between the variable in the control and the experimental is the variable that is being tested. In this experiment the Variables Control Group Experimental Group Iodine Time Amount of Iodine Starch Solution Starch solution Temperature of water Temperature of water Dialysis tubing Dialysis tubing Beaker Beaker Water water Time Table 1: This is the table showing the experimental design. The following is a set of step-by-step…

Determining Percent Composition of Unknown Copper Ore Sample Iodine-thiosulfate Method: An Analytical Method The objective of this experiment is to eliminate all interfering species from a sample of unknown copper ore in order to later determine pure copper content. Copper ore can be found in a mineral that contains pure copper and other species that is mined and can later have copper extracted from them (Taher, 1999). To eliminate all interfering species, such as Iron, Arsenic, and…

“Empty your mind, be formless, shapeless--like water. Now you put water in a cup, it becomes the cup; you put water into a bottle it becomes the bottle; you put it in a teapot it becomes the teapot. Water can flow or it can crash.Be water, my friend.”-Bruce Lee. Water can obtain many ways, but the most dominated ways are tap, water that is usually received from a person's home that originates from a water plant or well on the personal property. Or bottled water, water that is purchased from a…
