Carbohydrates, especially starch, which is a polysaccharide carbohydrate. Starch turns deep purple when tested with iodine.
No, iodine would not be effective for testing the presence of lactose. Iodine is typically used to detect the presence of starch, not lactose. To test for lactose, you would typically use reagents like Benedict's solution or glucose test strips.
Povidone iodine should not be used for patch testing as it contains other additives that may cause irritation or interfere with the test results. Tincture of iodine is a pure form of iodine that is more appropriate for patch testing for potential allergic reactions.
Himalayan salt contains very small amounts of iodine, significantly less than iodized table salt. It is not a reliable source of iodine and should not be used as the sole source of this essential nutrient in the diet. It is recommended to consume other iodine-rich foods, or use iodized salt for adequate iodine intake.
Yes, iodine is added when testing for starch. Iodine will change color to blue-black in the presence of starch. This color change helps to indicate the presence of starch in the substance being tested.
The conclusion of testing iodine and starch in an experiment is typically that a blue-black color change indicates the presence of starch in the solution. This is due to the formation of a complex between iodine and starch molecules. The test can be used as a qualitative test for detecting the presence of starch in a sample.
Yes. Iodine is a necessary nutrient.

Use 'I2 + KI ' solution: 0.1% 'Iodine-Iodide' turns purple blue with starch, very sensitive test!
By testing whether adding iodine darkens it.
iodine
The liquid used to test for starch is called iodine solution. Iodine solution turns a blue-black color in the presence of starch.
Iodine is a necessary nutrient for healthy thyroid function.
Fluoride, selenium, sodium, iodine, copper and zinc are not macronutrients
Careers where knowledge of nutrient testing would be useful include dietitians/nutritionists who use it to assess nutrient deficiencies in patients, food scientists who ensure food products meet nutritional standards, and agricultural scientists who analyze soil nutrients to improve crop production.
