medications used for this are Tapazol and Propyl-Thyracil. Radioactive iodine is taken either as a liquid or in capsule form and is used to destroy the thyroid gland or any other thyroid cells. The duration of the treatment can be extended to 8-18 months. The surgery that is mainly used for Graves’ disease is called Thyroidectomy. This is a procedure that removes a portion or all of the thyroid gland. If you have had radioactive iodine treatment or surgery‚ you will need to take replacement thyroid hormones

Thermometer Spotting tiles Pipette Water baths (at different temperatures) Iodine Measuring cylinder Method: 1. Collect equipment and set up as shown in diagram. 2. Fill a boiling tube with 10cm of starch and another with 5cm of enzyme. 3. Place both in a water bath at 20 degrees. 4. Wait until both test tubes reach equilibrium‚ test this with a thermometer. 5. Fill 30 spots on the spotting tile with 2 droplets of iodine. 30 spots are enough for 15 minutes‚ which is the maximum time the reaction

Once we had those three in the gradated cylinder we put 10mL of iodine in a test tube and we placed both in the 500 mL beaker with thermometers in each solution to ensure that they were all the same temperature when we added the iodine. As soon as all the solutions reached the desired temperature (22 degrees Celsius) we poured the iodine into the graduated cylinder and started timing the reaction. 6. As soon as the reaction stopped‚ we stopped

1. Introduction: This lab focused on showing the reaction that takes place between zinc and iodine using only deionized water instead of acetic acid (or vinegar) as we did in the previous lab by adding acetic acid to zinc iodide. The purpose of this lab was to see how water created the reaction and another compound or precipitate. Focus Question: Zn(OH)2 was the product when zinc and iodine were reacted without the presence of acetic acid in the water. Confidence Report: I am confident that

releasing carbon dioxide. Osmosis is a special type of diffusion‚ which occurs when water is diffused across the membrane. This can be affected by how hydrophilic a solute is on either side of the membrane. The diffusion of glucose‚ starch‚ and iodine was observed when the solutes went from a higher concentration of their individual solute to a lower concentration diffusing threw pores in the dialysis bag. The experiment sought to find out which solutes would diffuse threw the pores of the dialysis

prepared by dissolving 0.10 gram in 100 mL of water. The Eo’ value for this indicator is 0.53V. (n = 2) What is the useful voltage range of this indicator? (B) Starch indicators are useful when iodine titrations (organic oxidations) are performed. Why is it considered an advantage in these titrations to have iodine as the titrant instead of the analyte? 3.
