Iodine (a halogen) forms a starch-iodine complex by binding with amylose coils, which results in a transfer of charge between amylose and iodine, changing the energy levels of iodine atoms, and producing a dark blue color.

∙ 10y agonothing because when the amylase is added to the starch id digests it and produces maltose

Why does iodine react with sugar?
Iodine does not react with sugar, it reacts with starch.
What indicator substance is used to test a leaf for starch?
Iodine Solution is used to determine whether starch is present.
Will whole milk expect to react with a color change if mixed with iodine potassium iodide solution?
Any reaction; iodine is used to test the contamination with starch.
What is in Iodine solution?
It tests for starch
What is Iodine solution?
It tests for starch
What is the difference between iodine solution and starch solution?
Starch is insoluble in water. The commonest kind of iodine solution is known as tincture of iodine, which is an orangey-brown liquid. Please see the links.
What chemical is used to test for starch and what is the result if starch is present?
The chemical is called Iodine solution. If starch is present, the iodine solution will turn from amber to blue black.
What substances in the bond paper does the iodine painted on the skin react?
starch starch
Does iodine react in hydrochloric acid solution?
Iodine will will not react with hydroelectric acid
What parts of a leaf does not react to iodine?
then starch is not present...
A leaf was taken from a plant boiled with ethanol and tested with iodine solution what is it tested for?
Starch, I think, because iodine solution is the test for starch.
What is the difference between starch solution and iodine solution?
Starch is composed of amylose and amylopectin, and is not soluble in water due to the presence of amylopectinIodine (I₂) is somewhat soluble in water, but is more soluble in iodide (I⁻) solutions, such as potassium iodide solution (KI).Aqueous iodine molecules (I₂) and iodide ions (I⁻) together will form triiodide ions (I₃⁻), which can react with amylose found in starch to produce a deep-blue colour in the solution. So all of iodide (I⁻), iodine (I₂) and amylose (or starch) are required together to produce the colour.This can be used to test for:Amylose/Starch: Add iodine dissolved in potassium iodide solution to test solution, orIodine: Add starch and potassium iodide solutions to test solution.If the substance being tested for is present, then triiodide ions (I₃⁻) can react with amylose (in starch) to produce a deep-blue colour, that is, a positive result.
