Journal of Chemical Society , Volume 100: Number 9, September 2023 ***______{For Hard Copy, Please visit Library.}________*** Abstract: 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. acids/bases| organic chemistry https://doi.org/10.1021/acs.jchemed.3c00113 PER 0 0 0 0 RIEBPL RIEBPL 2024-01-17 0 2024-01-17 00:00:00 2024-01-17 PER 45313 45312
