To compare the width of the black iodide starch complex of each potato block, we need to follow these steps:

1. Start by obtaining potato blocks of similar size and shape. This will ensure that any differences in the width of the black iodide starch complex are not due to variations in the potato blocks themselves.

2. Prepare a solution of black iodide starch by mixing iodine solution with a starch solution. This solution will react with the starch present in the potato blocks and form a black complex.

3. Cut each potato block into thin slices of equal thickness. This will allow for a more accurate comparison of the width of the black iodide starch complex.

4. Dip each potato slice into the black iodide starch solution, ensuring that the entire slice is covered. Leave the slices in the solution for a specific amount of time to allow the reaction to occur.

5. Remove the potato slices from the solution and rinse them with water to remove any excess iodine solution.

6. Place the potato slices on a white background and observe the color of the black iodide starch complex. Measure the width of the complex using a ruler or caliper.

7. Compare the width of the black iodide starch complex of each potato block. Note any differences in width between the blocks.

The width of the black iodide starch complex may vary between the potato blocks due to several factors. These factors include the concentration of starch in each potato block, the amount of iodine solution absorbed by each block, and the time the potato slices were left in the black iodide starch solution.

By following these steps, we can accurately compare the width of the black iodide starch complex of each potato block and determine any differences between them.
