How to make PH indicator using cabbage?
If you have ever cooked a red cabbage, you certainly remember the dark blue-purple color of the cooked red cabbage and its juice. If you add a few drops of lemon juice to the dark purple cabbage, it immediately changes color and becomes red. We can use such color change to make a pH indicator.
 Project description
In this project you will use red cabbage to make a pH indicator. This is an easy, fast and very educational project for everyone who likes chemistry. All materials needed to build pH standards and the red cabbage itself are usually available locally in most places.
