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.
Water has a higher pH than cabbage juice. Better? I wish I know what cabbage juice's pH was but the stupid internet won't let me find it. Just gives me links to cabbage juice indicators. The lower the pH, the more acidic it is. 7 pH is pure water.
No, but when you mix the two together with water it does change colors to a sort of blue.
I've tried this before( hard to believe) it turns it a pinkish reddish color
