The density of cabbage juice can vary depending on factors such as the concentration and preparation method, but it typically ranges from about 1.0 to 1.1 grams per cubic centimeter (g/cm³). This is similar to the density of water, as cabbage juice is primarily composed of water along with dissolved nutrients and pigments. For precise measurements, laboratory testing would be required.

There is no such thing as purple cabbage juice because red cabbage juice is actually already purple, its just called red cabbage jucie.
When adding tomato juice to cabbage juice, the cabbage juice turns redish
no it reacts only with rainbow cabbage juice and not red

Which is more accurate- the pH paper or the red cabbage juice and why?
no
Cabbage juice is a natural pH indicator that changes color when mixed with acids or bases. When a base is added to cabbage juice, it typically turns a greenish-yellow color. This color change occurs because the pigments in the cabbage juice, known as anthocyanins, react to the pH change.

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.
