Iodine deficiency

present in different sample solutions. The tests were the iodine test, Benedict’s test, and the biuret test. To begin, the iodine test was used to identify which solutions contained glycogen or starch. If the solution tested negative, it stayed the yellow colour of the iodine solution. Whereas, if the solution tested positive for glycogen it turned a red-brown colour (Morris, 1946). Additionally, the solution turned a blue-black colour if the iodine reacts starch (Bailey & Whelan, 1961). For…

count, liver panel and serum glucose with electrolyte levels that may show signs of thyrotoxic crisis (Crawford & Harris, 2012, p. 47). Regular follow-up appointments should be scheduled and the nurse should teach the patient to avoid foods high in iodine (Crawford & Harris, 2012, p. 47). “Patients with Graves disease should notify their healthcare provider if they develop periorbital edema, eye irritation, blurred vision, and excessive tearing worsened by exposure to cold, wind, or bright…

Nutrient Testing Lab Purpose: Test different food items to see if certain nutrients are present. Hypothesis: if iodine, paper or certain solutions is present in the foods we test then it has one of the nutrients because it is detectable by a black, blue, yellow color when they are applied. Materials: flour, gelatin, milk, Iodine, brown bag, honey, cooking oil, potatoes, test tubes, peanut butter, eggs, paper towels, Chem-plate, hot water bath, Biuret's solution, Benedict's solution, chocolate…

Experiment Summary The purpose of this experiment was to determine the copper content of brass using iodometry. This was accomplished by creating a thiosulfate solution and standardizing it by titrating using a known amount of KIO3. The second part of the experiment involved preparing a brass sample and allowing copper to react with excess iodide to form I2. The resulting I2 was then titrated with the thiosulfate standard. Both the molar concentration of thiosulfate and the weight % copper…

A.2. Procedures for proper storage of the classroom chemicals General Requirements for Classroom Chemical Storage Store all chemicals inside a locked cabinet with sturdy shelves. Label cabinet with warning label and contents. Secure cabinets and shelving to the wall or floor. Segregate chemical storage away from students in a ventilated, locked storeroom. Chemical Segregation Store acids in a labeled, locked, corrosion resistant cabinet. 1 M hydrochloric acid, HCl acid; storage code: White.…

it to the first drop of iodine in the spotted white tile. 12. I noted the colour. 13. I discarded the mixture in the eye dropper and got a new drop from the test tube. I tested it with the second drop of iodine. It was important to always get a fresh drop of the mixture from the test tube since it cooled rapidly. 14. I repeated the test at 10 second intervals until I reached the endpoint of the reaction, the point at which the mixture remained the same colour as the iodine solution. 15. I…

unstable, interhalogens that seemingly violate the octet rule. Synthesis reaction: KClO3 + I2 + 6HCl → KCl + 2ICl3 + 3H2O Decomposition reaction: I2Cl6 → 2ICl + 2Cl2 The halogens used within this experiment consisted of Iodine and Chlorine to produce an oxidizing reagent Iodine trichloride. Due to electron orbitals and their interactions…

Vitamins are a small group of small molecular compounds that are vital in multi-cellular organisms; particularly humans. Ascorbic acid, which is commonly known as vitamin C is naturally present in some foods, added to others, and available as a dietary supplement. Vitamin C is an antioxidant and a lack of vitamin C can result in variety of illnesses. A common illness from a lack of ascorbic acid is; scurvy. Scurvy causes edema of the gums, exhaustion, and sometimes ulcerations of the gums.…
