Red cabbage is rich in a pigment called Cyanidin, which is one of several anthocyanidin pigments found in plants. Due to it's chemical structure, the molecule is easily able to add and remove -OH ions from itself. When an -OH is added to the molecule, the electronic configuration of the whole molecule changes. The electrons actually interact with the light and produce colors. Because of this, the color of the molecule is directly tied to the electronic configuration and changes when the -OH is added or removed. Remember, acids remove -OH ions and bases add -OH ions, which is why this compound serves as an indicator. So in the presence of a base, the OH is added to the cyanidin molecule, the electronic configuration changes, which changes the way it interacts with light and makes the molecule turn blue. An acid removes the OH, and it turns red. See the source links for more complete info.

Why does the color of red purple cabbage extract change its color when cooled?
I've never heard of it changing color when it is cooled, but it does change color with pH, and can be used as an indicator for acids and bases.See the Web Links for more information about using cabbage color as a pH indicator.
How does an acid react to red cabbage juice?
It is an acid, because Red Cabbage Juice is an indicator, and White Vinegar is an acid.
What color does red cabbage juice change to when adding tooth paste?
Because tooth paste is a base because anything that turns a blue or green when mixed with red cabbage juice(indicator) is a base.
What color does baking soda change when mixed with cabbage juice?
It will turn either blue or green, both a hue of blue. The reason of this is that Red Cabbage Juice is an indicator, which is used to see wether an object or chemical is an acid or a base. If the object is an acid it will turn a hue of pink, and if it is a base, it will turn a hue of blue. Which is why baking soda mixed with Red Cabbage Juice will turn blue or green.
What color does cabbage juice turn if you add base to it?
Cabbage juice is a natural pH indicator that changes color when mixed with acids or bases. When a base is added to cabbage juice, it typically turns a greenish-yellow color. This color change occurs because the pigments in the cabbage juice, known as anthocyanins, react to the pH change.

Why might red cabbage juice be a different color in vinegar than in baking soda?
Red cabbage juice is a natural pH indicator that changes color based on the acidity or alkalinity of the solution. In vinegar, which is acidic, the cabbage juice turns red or pink. In baking soda, which is alkaline, the cabbage juice turns blue or green. This color change is due to the interaction between the pigment molecules in the cabbage juice and the different pH levels of the solutions.
Is phenolphthalein in cabbage juice?
Phenolphthalein is not naturally present in cabbage juice; however, cabbage juice can serve as a pH indicator due to the presence of anthocyanins, which change color based on acidity or alkalinity. When cabbage juice is mixed with a basic solution, it will typically turn a greenish-yellow color, while in acidic solutions, it may appear reddish-purple. If phenolphthalein is added to cabbage juice, it could alter the color response based on the pH level of the solution.
What happens when sodium hydroxide is added to red cabbage juice?
When sodium hydroxide is added to red cabbage juice, the cabbage juice will change color. The cabbage indicator will turn from red/pink to blue/purple because sodium hydroxide is a strong base, causing a shift in the pH of the solution. This color change is due to the anthocyanin molecules in the red cabbage juice reacting with the change in acidity.
What color does beetroot indicator turn when an alkali is added?
i turns yellow and it turns pink when you add acids
What colour does alkali turn in cabbage?
Alkalis turn red cabbage juice blue/green/yellow.
Is cabbage juice an acid base or neutral?
it is an indicator.
What color does cabbage juice turn in a base?
Cabbage juice changes color in a basic solution, turning from purple to green or blue. This is due to the pH indicator properties of anthocyanins in the cabbage, which shift in color depending on the acidity or basicity of the solution. In more alkaline environments, the pigments reflect different wavelengths of light, resulting in the color change.
What color does red cabbage juice change to when adding tooth paste?
Because tooth paste is a base because anything that turns a blue or green when mixed with red cabbage juice(indicator) is a base.
