because....i don`t know!!
Nothing, but red cabbage is a simple pH indicator at home (red in acidic solutions).

Red cabbage is used as an indicator due to its anthocyanin pigments. These pigments change color based on the pH of the solution they are in. In an acidic solution, red cabbage turns red/pink, while in a basic solution it turns blue/green. By observing the color change, the acidity or alkalinity of a solution can be determined.
Anthocyanin is a natural pigment found in many fruits and vegetables such as red cabbage, berries, and grapes. It can act as a pH indicator, changing color in response to changes in acidity or alkalinity.
because you get more colour
Red Cabbage and Beetroot can be used but what else?
Filtration
No, it is natural, coming from "red cabbage".
The red-cabbage indicator smells like cabbage, nothing else...

Lemonade will turn pink when red cabbage indicator is added to it. This color change is due to the red cabbage indicator being sensitive to pH levels. The acidity of the lemonade will cause the red cabbage indicator to change color to pink.
If you blend red cabbage with water (the best ratio for this is 1:2, one cabbage leaf for two cups of water) and then add toothpaste the mixture will turn green. This indicates that toothpaste is a base. If you add vinegar instead the solution will turn red, indicating an acid.

Red Cabbage
Red cabbage is often used in the chemical industry as a natural pH indicator due to its color-changing properties. It can be used to determine the acidity or alkalinity of a solution by observing the color change of the cabbage juice when mixed with the solution.
yes I've done it for a science project
