To neutralize purple cabbage juice, which is a natural pH indicator, you can add an acidic substance such as vinegar or lemon juice. The acidity will change the color of the juice from purple to pink or red, indicating that the pH has become more acidic. Alternatively, adding a basic substance like baking soda will turn the juice green or blue, showing a shift towards a more alkaline pH. Always add the neutralizing agent gradually and mix well to observe the color change.

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.
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.
