Universal indicators are usually mixtures of several indicators. The easiest universal indicator to prepare is red cabbage juice. Stew red cabbage in water and pour off the water for use as an indicator solution. The pigment in red cabbage juice is anthocyanin, which changes color from red in acid solution to purplish to green in mildly alkaline solution to yellow in very alkaline solution. The color changes for red cabbage juice are shown to the right. read less
