Sure, here is the step-by-step process for the chemical test for starch:

1. First, you need to obtain a sample of the substance you want to test for starch. This could be a piece of food, a leaf from a plant, or a solution containing a suspected starch.

2. Next, you need to add a few drops of iodine solution to the sample. Iodine solution is usually a brownish-yellow color.

3. Observe the color change. If the sample contains starch, the iodine solution will react with it and change color to a blue-black.

4. If no color change is observed, then the sample does not contain starch.

This test is based on the reaction between iodine and starch to form a starch/iodine complex which is blue-black in color. This is a simple and effective way to test for the presence of starch in a sample.
