A chemistry class is experimenting with iodine to see which common white powder items will react and make the iodine change color which list item listed will have a chemical reaction with iodine how did sugar baking soda cornstarch soft

Sugar would have a chemical reaction with iodine.

To determine which item on the list will have a chemical reaction with iodine, I will break down each item and its chemical properties:

1. Sugar (sucrose): Sugar is a carbohydrate composed of carbon, hydrogen, and oxygen. It is unlikely to react chemically with iodine.

2. Baking soda (sodium bicarbonate): Baking soda is a compound that contains sodium, hydrogen, carbon, and oxygen. When combined with an acid, such as vinegar, it can undergo a chemical reaction, but it is unlikely to react directly with iodine.

3. Cornstarch: Cornstarch is a complex carbohydrate composed of long chains of glucose molecules. Similar to sugar, it is unlikely to undergo a chemical reaction with iodine.

4. Soft: It is unclear what "soft" refers to. If it refers to a soft white powder commonly found in household items, please provide additional information.

Based on the information provided, neither sugar, baking soda, nor cornstarch are expected to have a chemical reaction with iodine.
