It will turn a red color indercating that is has got acid in it
It turns blue or green.
Red cabbage juice is a natural pH indicator that changes color based on the acidity or alkalinity of the solution. In vinegar, which is acidic, the cabbage juice turns red or pink. In baking soda, which is alkaline, the cabbage juice turns blue or green. This color change is due to the interaction between the pigment molecules in the cabbage juice and the different pH levels of the solutions.
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.
Natural indicators : -Red cabbage solution(juice) -Strawberry solution -Cherry solution -Rose solution You can use any of these as an indicator, and you'll get the same result, here's how : after gaining the vegetable/rose juice, drop some of it on any solution and you'll get the results : the purple cabbage juice turns red when it is mixed with something acidic and turns green when it mixes with something basic.

If the pH of a detergent is usyally greater then 7 the juice of red cabbage become blue to green in this solution.
...indicator. (Or, the juice of a cabbage. :) )
Cabbage juice turns red due to the presence of anthocyanins, which are natural pigments found in red cabbage. These pigments change color based on the pH of their environment; they appear red in acidic conditions and greenish-yellow in alkaline conditions. When the juice is mixed with acidic substances, such as vinegar or lemon juice, it produces a red hue.
