Solution

Red cabbage indicator:

  1. A purple-colored solution called the red cabbage indicator is used to determine if a substance is acidic or basic.
  2. The pH indicator solution is made from red cabbage, which is often found in households.
  3. Flavin which is commonly known as anthocyanin, is a pigment molecule found in cabbage that changes color based on the acidity of the solution.
  4. When the purple solution comes into contact with an acidic substance, it changes red, and when it comes into contact with a basic substance, it turns green.
  5. A substance that is neutral in nature does not change color.

Therefore, the Red cabbage indicator turns green in basic solutions.
