A red cabbage indicator is a liquid made from mashed up red cabbage which you then put in a liquid to see whether it is acidic or not.
If it is acidic the liquid would turn reddy orange and if it was an alkali ( the opposite to acid) it would turn purpley blue.
This is if the liquid was clear in the first place.
No, it is natural, coming from "red cabbage".
The red-cabbage indicator smells like cabbage, nothing else...
Nothing, but red cabbage is a simple pH indicator at home (red in acidic solutions).
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.

It is important to release a liquid.
put small pieces of purple cabbage in hot water and stir it and leave it for 20 min and take only water. if indicator turns substance red it is acidic ,if blue then basic if no change then neutral

It is an acid, because Red Cabbage Juice is an indicator, and White Vinegar is an acid.
