Color. Adding food coloring to batter or to your icing involves a chemical reaction of the two products bonding together. This bonding process starts when you add the color and mix it in, but it doesn’t end straight away as the color needs some time to fully integrate and settle. Complete answer: Chemical changes occur when the substance’s composition is changed. When bonds are broken and new ones are formed a chemical change occurs. When two or more reactants are mixed and a change in temperature, color, etc. is noticed, a chemical change is probably occurring. A change in color is not always a chemical change.Sep 17, 2022 · The color of chemicals is a physical property of chemicals that in most cases comes from the excitation of electrons due to an absorption of energy performed by the chemical.
