The color remain red because vinegar is an acidic solution.
It usually takes approximately 4 drops.

You can make a PH indicator solution out of blueberry juice, or you can buy litmus paper or use an indicator solution that you can buy at the store.
This solution is soda water containing carbon dioxide.
Staying red, because of the acidic properties of orange juice (pH < 4)
Cabbage contain Anthocyanins called Cyanidin. These are responsible for changing color with pH. Changing the pH affects the shape of the molecule which, in turn, changes its wavelength absorption.
Red in acidic solution
Citric acid mixed with cabbage juice turns the solution red/pink in color. This is due to the natural pigment in red cabbage, anthocyanin, which changes color in response to changes in pH levels.
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.
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.
Red cabbage is often used in the chemical industry as a natural pH indicator due to its color-changing properties. It can be used to determine the acidity or alkalinity of a solution by observing the color change of the cabbage juice when mixed with the solution.
It will turn a red color indercating that is has got acid in it
pink
no it reacts only with rainbow cabbage juice and not red
at first it will turn purple then it will turn pink
Red cabbage juice contains a class of chemical compounds known as anthocyanins. The color of anthocyanin molecules in solution depends on how acidic or basic the solution is. In a strongly acid solution, anthocyanins will appear red. In a neutral solution, anthocyanins appear purple. In weakly basic solutions anthocyanins appear blue, while in strongly basic solutions they will appear green. In extremely basic solutions, the anthocyanins will appear yellow. Because ammonia is a base, spraying ammonia into a glass containing cabbage juice (which contains anthocyanins) will most likely turn green.
Cabbage juice contains a water-soluble pigment called anthocyanin that changes color based on the pH of the solution. When you exhale into cabbage juice, carbon dioxide mixes with water in the juice, creating carbonic acid and lowering the pH. This acidic environment causes the anthocyanin to change color, usually turning from purple to pink or red.
