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. An environmental chemist is going to field test the chemical oxygen demand factor for a stream in Yellowstone Park.

Concentration of Sodium Chloride and the Rate of Reaction of Enzyme Amylase Research Question: How will changing the percentage of sodium chloride concentration affect the rate of reaction of enzyme amylase‚ measured using the absorbance of starch and iodine with a spectrophotometer. Introduction: Amylase is an enzyme that is involved in the human digestive process. Found in both the human pancreas and the human saliva‚ amylase breaks down starch into sugar so that large molecules can be easily digested1

infection. Causes of Hypothyroidism Radiation therapy can also cause hypothyroidism. When radiation damages the cells‚ the thyroid gland has to work harder. Radioactive iodine treatment can also destroy the thyroid gland. Surgery and medications can also cause an underactive thyroid. The human body does not produce iodine‚ and iodine deficiency can cause hypothyroidism.
