Answer:

A chemical test for starch is to add iodine solution (yellow/brown) and look for a colour change. In the presence of starch, iodine turns a blue/black colour. It is possible to distinguish starch from glucose (and other carbohydrates) using this iodine solution test.

Answer:

Starch test is carried out to confirm the presence of carbohydrate in the solution.

Starch, a carbohydrate, can be identified by a positive iodine test.

Explanation:

A few drops of iodine solution are added to a raw or boiled sample of the substance suspected of containing starch. If starch is present, the substance will turn blue-black in the area where the iodine solution touches it.
