Is changing color of a carnation a chemical or physical change?
It is a chemical change.
Is changing of color a sign of chemical change?
The change of color may be a sign of a chemical reaction.
Is color changing in leaves a chemical change or a physical change?
Color changing in leaves is a chemical change. It involves the breakdown of chlorophyll and the production of other pigments due to chemical processes triggered by factors like temperature and daylight changes. This results in the visible color change in the leaves.
Is bleach changing the color of your shirt a physical change?
No, bleach changing the color of a shirt is a chemical change. The active ingredient in bleach, sodium hypochlorite, reacts with the dyes in the fabric, breaking them down and removing their color. This results in a permanent change in the chemical composition of the fabric.
17 Explain how color can be classified as both a physical property and as one indication of a chemical change?
Color can be classified as a physical property because it can be observed without changing the chemical composition of a substance. However, color change can also indicate a chemical change when it is a result of a reaction that alters the molecular structure of the substance, leading to a new chemical identity. In this case, the color change is a visual representation of the chemical transformation that has occurred.

Is leaves changing color chemical reaction?
Yes it is chemical change.
Do acids effect indicators?
Yes, acids can affect indicators by changing their color. Indicators are substances that change color in response to the acidic or basic nature of a solution. Acids can cause indicators to change color depending on their pH level.
Is bleach changing the color of your shirt a physical change?

Is phenolphthalein a chemical property or a physical property?
Phenolphthalein itself is a chemical. It changing color is a chemical change.
Is an indicator's reaction in acids and bases a chemical change?
No, an indicator's reaction in acids and bases is a physical change. Indicators change color based on the pH of the solution they are in, but the chemical composition of the indicator remains the same.
Is changing color of apple a chemical or physical change?
Changing the color of an apple is a chemical change because it involves a chemical reaction that alters the molecular structure of the apple's pigments, such as when the apple oxidizes and turns brown.
Is changing color of a carnation a chemical or physical cange?
Changing the color of a carnation by adding food coloring is a physical change, as it does not alter the chemical composition of the flower. The dye molecules simply adhere to the petals, giving the appearance of a different color.
