Yes, cabbage juice can change color when mixed with alum due to the pH changes that occur. Cabbage juice contains anthocyanins, which are pH-sensitive pigments. When alum, a basic compound, is added, it can alter the acidity of the solution, causing the cabbage juice to shift from its original color to shades of green or blue, depending on the concentration. This makes it a useful natural indicator for pH levels.

This color change is due to the anthocyanin molecules in the red cabbage juice reacting with the change in acidity.
What color does cabbage juice turn if you add base to it?

Yes, adding dish soap to cabbage juice causes a chemical change. Cabbage juice contains anthocyanins, which are natural pH indicators that change color based on acidity or alkalinity. When dish soap is added, it alters the pH of the solution, resulting in a color change that indicates a new chemical environment. This transformation is not just a physical change but involves a chemical reaction due to the interaction of the soap with the compounds in the cabbage juice.

Why does calcium carbonate react when put in cabbage juice?
Calcium carbonate reacts with cabbage juice because the juice contains anthocyanins, which are pH-sensitive pigments. When calcium carbonate is added to cabbage juice, it reacts with the acids present in the juice, leading to a change in pH. This reaction can cause a color change in the juice, demonstrating the acid-base interaction. The presence of calcium carbonate neutralizes the acidity, resulting in a shift in the color of the cabbage juice, which can range from pink to green depending on the pH level.
