生活中处处充满手性之美,为了让大众正确认识手性,本文基于L-和D-酒石酸对映异构体的差异,设计实验开展科普教育:(1)酒石酸的分子模型搭建;(2)酒石酸晶体的培养与观察;(3)酒石酸溶液的旋光性观察;(4)酒石酸分子的手性拆分.科普深入浅出,实验操作简单,现象明显,互动性强,早期科普工作反响良好.
Unveiling the Mystery of Chirality from Tartaric Acid
Chirality permeates every aspect of life's beauty.To foster a proper understanding of chirality among the public,this paper employs the differences between L-and D-tartaric acid enantiomers to design experiments for popularization of science:(1)Construction of molecular models of tartaric acid enantiomers;(2)Cultivation and observation of tartaric acid crystals;(3)Observation of the optical activity of tartaric acid solutions;(4)Recognition of chirality in tartaric acid molecules.These experiments range from basic to advanced,featuring simple operation,obvious phenomena,interactive communication,and have received positive feedback in the early stages of implementation.
