✨The SCIENCE ✨
The purple cabbage in this activity is acting as a pH indicator. A pH indicator is a substance that change colour depending on the acidic conditions it is present in. Red cabbage contains a water-soluble pigment called anthocyanin, which changes color when it is mixed with an acid or a base. In this case, the colour of red cabbage juice changes to a bright pink/red❤️ in the presence of acids (like the lemon juice), and changes to a dark blue/green💙 in the presence of a base.
