Indicating PH using Red Cabbage

Thanks to our Science Teacher Ms. Victoria Merino, our students learnt how to identify different PH using Red cabbage so they could explore different alkalinity and acidity of different products. 

Do you want to try it at home? 

Remove the paper from the cabbage juice and hang it up by a clothespin to dry. Cut the dried paper into thin strips. Dip the strips into various liquids to test their pH. The redder the strip turns, the more acidic the liquid is.
