Answer:
Pouring hot water over a red cabbage would turn water into purple because the dye in the cabbage called anthocyanin is being extracted. This pigment is used as an indicator for acids and bases. When it is added to an acid, it changes the color of the solution into pink while it changes into blue when added to a basic solution.
By making it simpler for the pigment to dissolve in water by blending the cabbage leaves with warm water, you may extract it quickly.
