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 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.
Is baking soda mixed iodine solution a chemical change?
Chemical, When something changes in color, it is a sign of a chemical change.
Is iodine melting a chemical or physical change?
Iodine melting is a physical change, as it does not alter the chemical composition of the iodine. It simply changes from a solid to a liquid state due to the input of heat energy.
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.
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 baking soda with iodine solution a chemical or physical change?
physical because its a mixture and doesnt chemically combine
Is baking soda mixed iodine solution a chemical change?
Chemical, When something changes in color, it is a sign of a chemical change.
Iodine sublimes to iodine vapor is physical or chemical change?
Sublimation of iodine to iodine vapor is a physical change. It is a phase transition in which a substance goes directly from a solid to a gas without changing its chemical composition.
Is iodine melting a chemical or physical change?
Iodine melting is a physical change, as it does not alter the chemical composition of the iodine. It simply changes from a solid to a liquid state due to the input of heat energy.
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.
Is baking soda mixed with iodine a chemical or physical change?
Chemical Change
Is the heating of iodine crystals a chemical or physical change?
It is a physical change (sublimation).
Is baking powder mixed with iodine chemical or physical change?
This is a physical process.
Is iodine sublimating a chemical change?
Yes, the sublimation of iodine is a physical change, not a chemical change. Sublimation is the process by which a substance transitions from a solid directly to a gas without passing through the liquid phase. The chemical composition of iodine remains the same during sublimation.
Is iodine becomes a purple gas a chemical change?
Yes, iodine becoming a purple gas is a physical change, not a chemical change. A chemical change involves the formation of new substances with different chemical properties, whereas in this case, the iodine is just changing its physical state from solid to gas without forming any new substances.
