Can cabbage teach you about acids and bases?

Can cabbage teach you about acids and bases?

4C found out it can. They made an indicator solution using red cabbage and warm water and used it to find out if different substances were acids or bases. An indicator changes colour when you add an acid or a base. Some of the things we tried surprised us – did you know that Coke Cola and Shampoo can both be acidic? Tyler asked a great question “Why do people drink Coke if they know it’s acidic and can harm their teeth?”
