Cabbage juice contains a pH indicator called anthocyanin, which changes color in response to the acidity or alkalinity of a substance. When cabbage juice is mixed with aspirin, which is acidic, the anthocyanin reacts to the pH change, resulting in a pink color. This color change is a visual representation of the acidic nature of aspirin, demonstrating how natural indicators can be used to gauge pH levels.

This reaction can cause a color change in the juice, demonstrating the acid-base interaction. The presence of calcium carbonate neutralizes the acidity, resulting in a shift in the color of the cabbage juice, which can range from pink to green depending on the pH level.
