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.
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.
It turns blue or green.
There is no such thing as purple cabbage juice because red cabbage juice is actually already purple, its just called red cabbage jucie.

When red cabbage juice is mixed with baking soda, a chemical reaction occurs. The baking soda is a base and reacts with the anthocyanins in the red cabbage juice, causing a color change. The mixture will turn blue or blue-green due to the change in pH.
