What else can I help you with?
What happens if you put a drop of iodine on a piece of paper?
If you put a drop of iodine on a piece of paper, it will react with starch on the paper turning it blue-black. This is a common test for the presence of starch.
What is lugols iodine?
The Lugol solution has a brown color.
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.
Can rubidium react with iodine?
Yes. Rubidium is an alkali metal in the sodium group. It will react with iodine to form rubidium iodide:- 2Rb+ I2 -> 2RbI
How does iodine react with acid?
Iodine does not directly react with acids. However, when iodine is added to an acid solution, it can form hypoiodous acid (HOI) which is a weak acid. This reaction can be used in analytical chemistry to detect the presence of iodine.
What do lugols iodine solution nd clinitest tape for?
Lugols: tests for starch Clinitest- Glucose
What substance on the bond paper does the iodine painted on the skin react?
starch
What substances in the bond paper does the iodine painted on the skin react?
starch starch

What is lugols iodine?
The Lugol solution has a brown color.
With what substance in bond paper does the iodine painted on the skin react with?
glue, tape, staples, paperclips, and sometimes the sap of trees.
Do iodine and lithium bromide react?
Iodine and lithium bromide do not react with each other. However, iodine can form a complex with lithium ions in a solution containing lithium bromide.

How does iodine react with baby powder?
Iodine does not react with baby powder. Baby powder is usually made of talc or cornstarch, which are inert substances and do not participate in chemical reactions with iodine.
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.
