Not normally, it is just bicarbonate of soda.
When baking soda (sodium bicarbonate) is mixed with iodine, a chemical reaction does not occur. Baking soda is a base and iodine is a nonpolar molecular compound, so they do not react with each other.
Baking powder, baking soda, or iodine.
In my science lad the mixture turned red. I don't know if it is the white colour of the baking soda making the iodine lighter or if it were a chemical reaction.
A nonhomogeneous mixture is obtained (for solids).
Chemical Change
baking soda reacts with vinegar to produce sodium acetate and carbon dioxide
Its a physical change as there is no reaction.
Aluminum powder can react with iodine to form aluminum iodide. This reaction is exothermic and can produce purple fumes of iodine vapor.
I assume that the questioner means what happens when iodine and baking soda (sodium bicarbonate or NaHCO3) are mixed in water. Whether the components are mixed in water or not, no chemical reaction would take place. If added to water, both the iodine and baking soda would dissolve, and the water would become a dark, reddish-brown. Iodine usually acts as an oxidizing agent, but iodine does not oxidize baking soda because the carbon atom in baking soda already has a formal charge of +4, and oxygen is a more powerful oxidizer than iodine.
To make deodorant with iodine, you can mix a small amount of iodine tincture with coconut oil and baking soda to create a paste. Combine one tablespoon of coconut oil with one teaspoon of baking soda and a few drops of iodine, adjusting the consistency as needed. Apply the mixture to your underarms, ensuring even coverage. Always do a patch test first to check for skin sensitivity to iodine.
Chemical, When something changes in color, it is a sign of a chemical change.
Baking soda and eating soda are not the same. Baking soda is an ingredient that is found in baking recipes.
