red cabbage juice indicator

Red cabbage juice contains a pigment molecule called flavin (ananthocyanin). Very acidic solutions will turn anthocyanin a red color. This pigment is also found in apple skin, plums, poppies, cornflowers, and grapes. Neutral solutions turn it a purplish color.



Basic solutions appear in a greenish-yellow colour.The color of the juice changes in response to changes in its hydrogen ion concentration.
