Is bread iodine solution a physical or chemical change?
Mixing bread with iodine solution to observe a color change is a physical change as it does not alter the chemical composition of the bread or the iodine solution. The color change occurs due to a physical interaction between the starch in the bread and the iodine molecules.
Is mixing sugar with iodine solution a chemical change or a physical change?
Mixing sugar with iodine solution is a physical change because no new substances are formed. The sugar and iodine solution retain their individual chemical properties even when mixed together.
Is mixing iodine and baking soda a chemical or physical change?
Its a physical change as there is no reaction.
Is iodine dissolves in alcohol a chemical or physical change?
When iodine dissolves in alcohol, it is a physical change because no new substances are formed. The iodine molecules are simply dispersed in the alcohol solution, but the chemical properties of iodine and alcohol remain the same.
What chemical is used to test for starch and what is the result if starch is present?
The chemical is called Iodine solution. If starch is present, the iodine solution will turn from amber to blue black.
Is mixing baking soda with iodine solution a chemical or physical change?
physical because its a mixture and doesnt chemically combine

Chemical properties of baking soda?
baking soda reacts with vinegar to produce sodium acetate and carbon dioxide

The chemical is called Iodine solution. If starch is present, the iodine solution will turn from amber to blue black.
What happens when you mix baking soda with iodine?
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.
Is black crystals of iodine turning into purple vapour of iodine a physical change or a chemical change?
The transformation of black crystals of iodine into purple vapor of iodine is a physical change. This is because the change does not involve a change in the chemical composition of iodine; it only involves a change in the physical state from solid to gas.
What chemical is used as a chemical indicator for the presence of starch?
Iodine is commonly used as a chemical indicator for the presence of starch. When iodine comes into contact with starch, a blue-black color change occurs, making it easy to visually detect the presence of starch in a solution.
