Demonstrations with Poinsettia Extract Indicator: Acid-Base Chemistry at Home During Winter Holidays
Journal of Chemical Education, v100 n9 p3731-3738 2023
Poinsettia ("Euphorbia pulcherrima") contains anthocyanins that dissolve in water and exhibit color changes due to changing pH. This property makes the poinsettia extract a useful acid-base indicator for pH demonstrations. When combined with common household materials, this experiment can be used as an alternative low-cost tool in teaching acid-base chemistry and organic chemistry.
