Cabbage juice is used in the lab as a natural pH indicator due to its ability to change color in response to different acidity levels. The pigment, anthocyanin, present in red cabbage reacts with acids and bases, allowing students to visually identify pH changes. This makes it an effective and safe alternative to synthetic indicators in educational experiments. Additionally, it provides a hands-on way to explore concepts of acidity and basicity.
