Go Green! -pH Indicators in Red Cabbage

Experiments during Go Green lessons

The topic of the last Go Green class was the study of red cabbage, and the students had the opportunity to check its pH indicator. This vegetable contains a water-soluble pigment called anthocyanin that changes color when mixed with acid or base. In the first case, the color changes to red, and in the second, to a bluish-green hue.
