P1 – Task 1, M1 – Task 2, M2 – Task 3 Iodine Extraction Equipment:  Goggles  Fume cupboard  2X 250cmᶾ beaker  Filter funnel  Filter paper  Separating funnel  Bunsen burner  Tripod  Gauze Method: 1. Set up the equipment with the Bunsen burner and tripod on the heatproof mat with the gauze on top of the tripod. 2. Add the seaweed to the tin lid and place on top of the gauze (try not to use any ‘pods’ of seaweed as they pop when heated which could be dangerous). Light the Bunsen burner and…

out the order of reactivity of the Group 17 halogen elements using chlorine, bromine and iodine. Hypothesis: The higher on the periodic table the more reactive the element will be. Materials: Safety glasses 0.2M potassium chloride solution Black tray 0.2M potassium bromide solution Spotting tile 0.2M potassium iodide solution Teat pipette chlorine water Distilled water bromine water Iodine water Procedure:…

Thyroxine is an iodine-containing, thyroid hormone produced by the thyroid gland. Along with thyroxine, triiodothyronine is also produced in the thyroid gland. Thyroxine usually is converted into triiodothyronine by enzymes in target cells called deiodinases. Concentrations of thyroxine are usually greater in the body, but triiodothyronine is considered the major thyroid hormone. Thyroxine production is controlled by the pituitary gland. The hypothalamus will secrete thyrotropin-releasing…

specific technique that I chose to use is the iodine solution method. Despite there being many other viable options to this titration process, I chose the iodine solution method because the color change is easiest to detect when using juices. The other tests are simple when using clear solutions, but on juices, the color change 000166-XXX 6 is not as apparent due to the colors of the juices, making it harder to get accurate results. Other than iodine, one of the most commonly used titration…

Introduction: The objective of this lab experiment is to identify different macromolecules by carrying out three different tests such as iodine test, Benedict’s test and the biuret test. These three tests are going to examine different properties of macromolecules such as their bonds, and functional groups to identify the solution as one of the four macromolecules. The iodine test is used to determine the presence of polysaccharides such as starch and glycogen in the solution (Harisha, 2006).…

exam is going to be performed. The routes include Intrathecal which is occurring within or administered into the spinal theca (C, T, L spine). The Rate of injection should be done Slowly over 1-2 min and should not to exceed 300 mg/mL or 3060 mg iodine per single myelographic procedure. Another route of administrations is intravenously which is the method of route choice used for a excretory urography, digital subtraction and Angiocardiography: ventriculography, pulmonary arteriography,…

Q5: What foods are good sources of iodine? There a myriad of foods that are rich in iodine, including, but not limited to: salmon, oysters, packaged bread, iodised salt (far less reliable as far as sources go, due to the connection between iodised salt and other prevalent potential medical issues), and an assortment of dairy products, from milk, to yoghurt, to cheese. Q6: What can happen if you do not get enough iodine from the food you are eating? As iodine is not a naturally produced element,…

capacity, mixed with 20ml. of carbon tetrachloride, 30ml of glacial acetic acid and finally 1ml. of saturated potassium iodide solution. After well shaken for 1minute, 100ml. of distilled water was added to and thus free iodine liberated in the solution was titrated by 0.01N thiosulphate solution. 1 ml. of this. thiosulphate solution corresponds to 0.00008g. of oxygen. The acid ester used here was prepared from cuttle fish oil as described in the fore going paper and had…

The reaction between Propanone and iodine under acidic condition Aims To find the order of reaction with respect to propanone, iodine and sulfuric acid, thus proposing a rate equation. Find rate constant at various temperature and with the use of the Arrhenius equation, find the activation enthalpy of the reaction. General Method {For step by step guide of the experiment see preparation page} By using known concentration of aqueous iodine solution (0.000 moldm-3, 0.005 mol dm-3, 0.015…

comparison, students conducted Starch Testing and Carbohydrate testing. The starch testing consisted 6 tubes, two of which were controlled samples with and without a Lugol’s Iodine, two experimental samples with and without Lugol’s, Iodine, as well as one tube with water that contains Lugol’s Iodine. Each tube that contains Lugol’s Iodine had three drops of Lugol’s and ten drops of the other solution. The tubes without Lugol’s only have ten drops of the solution. To continue the Starch Testing,…
