Why you use starch as indicator in iodometric titration?
Because starch forms a dark blue colored soluble product with free iodine, so that the appearance of color in the solution from this reaction effectively shows when all the substances in the solution that react more strongly with iodine than does starch have been consumed and the titration is finished.
What food doesn't react with iodine?
It's very likely that Iodine will react with plant products, since Iodine reacts with starch. Negative controls (glucose, water, and protein) could be used to verify the result.

Why does starch react with iodine solution?
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.
What regent would you add to starch agar plate to detect starch hydrolsis?
To detect starch hydrolysis on a starch agar plate, you can add iodine solution. Iodine reacts with starch to form a blue-black color, and if starch is hydrolyzed by the organism, the clear zone around the bacterial growth will indicate the presence of amylase, an enzyme that breaks down starch.
What is the positive color reaction starch is present?
Use an iodine solution. it should be orange to brown to begin with, if there is a starch present, it will turn blue-black.
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 the color of potato cell if added with iodine solution?
