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
It will turn a red color indercating that is has got acid in it
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.
at first it will turn purple then it will turn pink
no it reacts only with rainbow cabbage juice and not red
When adding tomato juice to cabbage juice, the cabbage juice turns redish
Red in acidic solution
orange
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.
It is an acid, because Red Cabbage Juice is an indicator, and White Vinegar is an acid.
