What is Purple Cabbage as pH Indicator about?

This document describes how to make a homemade pH indicator using purple cabbage. To make the indicator, cut up purple cabbage and boil it in water to extract the pigments. This produces a colored water solution that can be used to test the pH of other solutions based on the colors that result, which are caused by anthocyanin pigments in the cabbage whose color changes with pH.
