it turns greenish yellow if it is added to a base
When adding tomato juice to cabbage juice, the cabbage juice turns redish
no it reacts only with rainbow cabbage juice and not red
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.
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.
i turns yellow and it turns pink when you add acids
Red cabbage juice is purple before it is added to anything.
...indicator. (Or, the juice of a cabbage. :) )
