Iodine can react with certain substances to produce a color change, typically turning blue or dark brown in the presence of starch. In your experiment, common white powder items that may react with iodine include:
1. **Starch** - If you have a starch powder (like cornstarch), it will react with iodine and turn blue.
2. **Baking soda (sodium bicarbonate)** - It generally does not react with iodine to produce a color change.
3. **Baking powder** - Similar to baking soda, it does not react with iodine to change color.
4. **Flour (wheat flour)** - While it may not produce a strong color change like starch, it can have some reaction with iodine due to the presence of starch in flour, potentially resulting in a faint color change.
Among these, pure starch is the most likely to produce a noticeable reaction with iodine, resulting in a deep blue color.
