Answer 2

Hi there. When you mix Iodine, a mineral found in some foods, and sodium bicarbonate (common name is baking powder) together with water, they will both dissolve and form a dark, reddish-brown solution. This is only a physical reaction and not a chemical reaction because the iodine does not oxidize baking soda.
