yay, great fun , and works for purple sprouting broccolit too. (in fact if you want to do some fun kitchen /garden chemistry, you can try all sorts of petals and veg. beetroot is good I seem to recall!)
oh yes , what colour?-- it goes turquoise in alkali and pink in acid. Bicarbonate of soda and lemon juice are all you need for a fun afternoon with your 8 year old.
Green
blue-pinky colour.
Because tooth paste is a base because anything that turns a blue or green when mixed with red cabbage juice(indicator) is a base.
Reversible
It is an acid, because Red Cabbage Juice is an indicator, and White Vinegar is an acid.
Green
When adding tomato juice to cabbage juice, the cabbage juice turns redish
Blue/green color
blue-pinky colour.
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.

no it reacts only with rainbow cabbage juice and not red
When tonic water is mixed with cabbage juice, it typically changes color from its clear or slightly cloudy appearance to a purple or pink hue. This occurs because cabbage juice contains anthocyanins, which are pH indicators that react to the quinine in tonic water. The resulting color shift indicates a change in acidity, demonstrating how natural pH indicators can be used in simple experiments.
