How did lugol solution get its name?
Lugol solution was named after the French physician Jean Lugol who first developed it in 1829. The solution is commonly used as a disinfectant and to test for the presence of starch in laboratories.
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.
Why is lugol's solution cannot detect simple sugar?
Lugol's solution is a reagent commonly used to detect the presence of starch. It cannot detect simple sugars because its active ingredient, iodine, does not react with simple sugars like glucose or fructose. Simple sugars do not contain the necessary chemical structure for the iodine in Lugol's solution to form a complex with, so they remain undetected in this test.
What is lugol solution used for?
Lugol's solution is used as an iodine supplement to treat iodine deficiency conditions like goiter and to prepare patients for thyroid surgery. It is also used as an antiseptic for cleaning wounds and as a stain for biological samples in laboratories.
Why would you wait 5 minutes before spraying Lugol's solution?
Comen sence you dip sticks

What is lugol's solution and how did it get its name?
Lugol's solution, is a solution of elemental potassium iodide and iodine in water. It is named after J. G. A Lugol a French physician.
What color is Lugol's solution prior to changing color?
Lugol's solution is a brownish-yellow color prior to changing to a dark blue-black color.
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 color will glucose turn when mixed with lugol's solution?
orange
How do you test foods to see if they contain starch?
Lugol's Solution
What color is Lugol's iodine?
Lugol's iodine is a reddish-brown color due to being a solution of elemental iodine and potassium iodide in water.
How does Lugol's solution work as an indicator?
An indicator is a substance that changes colour in the presence of another substance. Let say inside the beaker are substances of both glucose and starch. The glucose and starch are of same colour. By injecting the lugol's solution into the beaker, the lugol's solution changes colour in the area of where starch is, while no colour changes in the presence of glucose. Thus, by using the Lugol's solution which only acts as indicator for starch and not glucose, we could tell part which area floats around with glucose and starch substances. Lugol's solution works as an indicator because it will stain starches due to iodine's interaction with the coil structure of the polysaccharide.
What does lkl stand for?
Iodine-Potassium-Iodide - IKI - Lugol's Solution
What is the chemical equation for the preparation of Lugol's solution using potassium iodide and iodine?
The chemical equation for the preparation of Lugol's solution using potassium iodide and iodine is 2KI + I2 -> 2KI3.
Which particles-starch or Lugol's-were able to cross the model cell membrane?
The Lugol's solution particles were able to cross the model cell membrane, while the starch particles were too large to pass through. Starch is a large molecule that cannot diffuse across the membrane, while Lugol's solution contains smaller molecules (iodine and iodide ions) that are able to pass through.
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.
