A Red Cabbage pH Indicator Lab

Red Cabbage pH Indicator Lab

In our studies of soil, we learned how the pH level of the soil can greatly effect its fertility.  Today we used red cabbage to test the pH level of various liquids.  The red cabbage was boiled in water to create an indictor that changed the color of each liquid.  We could then estimate the pH by comparing the color to a key.
