Answer 2

Answer:

A test for the presence of starch in which the sample turns blue-black in color when a few drops of potassium iodide solution is placed on the sample.

Explanation:

The reaction is due to the formation of polyiodide chains from the reaction of starch and iodine. The amylose in starch forms helices where iodine molecules assemble, forming a dark blue or black color. When starch is broken down or hydrolyzed into smaller carbohydrate units, the blue-black color is not produced. Therefore, this test can also indicate completion of hydrolysis when a color change does not occur.
