What is the difference between lugols iodine and grams iodine?
Lugol's iodine is a mixture of elemental iodine and potassium iodide, commonly used as a disinfectant and as a supplement to support thyroid function. Gram's iodine, on the other hand, is a stain used in microbiology to differentiate between gram-positive and gram-negative bacteria based on their cell wall composition. The main difference lies in their applications and compositions.
What is the common name for iodine?
The common name for iodine is iodine.
What is the difference between iodine and povidone iodine?
Iodine is a chemical element, while povidone iodine is a complex of iodine and the polymer povidone. Povidone iodine is commonly used as an antiseptic due to its slower release of iodine compared to pure iodine.
Why starch reacts with lugols solution?
This solution is used as an indicator test for the presence of starches in organic compounds, with which it reacts by turning a dark-blue/black. Elemental iodine solutions like Lugol's will stain starches due to iodine's interaction with the coil structure of the polysaccharide. Starches include the plant starches amylose and amylopectin and glycogen in animal cells. Lugol's solution will not detect simple sugars such as glucose or fructose. In the pathologic condition amyloidosis, amyloid deposits (i.e., deposits that stain like starch, but are not) can be so abundant that affected organs will also stain grossly positive for the Lugol reaction for starch.

What is the chemical reaction between lugols solution and a starch?
The reaction between Lugol's solution (iodine) and starch forms a blue-black complex. Iodine molecules fit into the helical structure of starch molecules, producing this characteristic color change. This reaction is commonly used to test for the presence of starch in a solution.
What iodine supplement does Dr David Brownstein suggest?
Dr. David Brownstein often recommends the use of Lugol's solution, which is a combination of elemental iodine and potassium iodide, as an iodine supplement. He believes it can help support thyroid health and overall wellness. However, individuals should consult with their healthcare provider before starting any new supplement regimen.
What color will Lugols solution turn in the presences of lipds?
Lugol's solution will turn brown in the presence of lipids. This is due to the lipids reacting with the iodine in Lugol's solution, leading to the development of a brown color.
What does lugol's iodine?
it is iodine and potassium iodide solution It's a orange colored solution that consists of Iodine and Potassium Iodide and is used to test a substance for starch. If the color of the solution turns black when put on/in the substance, then the substance is positive for starch.
Differences between lugols iodine and grams iodine?
Lugol's Iodine = 20g Potassium Iodide + 10g Iodine dissolved in 1L H2O Gram's Iodine = 6.7g potassium iodide + 3.3g Iodine dissolved in 1L H2O Recipe's taken from Flinn Scientific Catalog I have on campus. Looks to me as Gram's is just a dilute version of Lugol's. Same ratio of KI:I just less of it. Couldn't tell you much about differences in application however.
Will apple juice be positive in a bendict's test or a lugols test?

What is the difference between iodine and povidone iodine?
Iodine is a chemical element, while povidone iodine is a complex of iodine and the polymer povidone. Povidone iodine is commonly used as an antiseptic due to its slower release of iodine compared to pure iodine.
Why does the concentration of iodine ions remains constant in the iodine clock reaction?
Iodine ion is not consumed; in the first step the iodine ion is oxidized to iodine, in the second step iodine is reduced to iodine ion.
