9350825 Whisnant The goal of this project is to complete the development of a series of general chemistry laboratory experiments which reflect the practice of modern chemistry. The two-semester series of experiments is structured as a set of multi- experiment projects which give students an early introduction to modern instruments and to the different fields of chemistry. A diode-array UV/visible spectrophotometer is being used for a discovery-based organic spectroscopy project in which 32 students record the spectra of a number of compounds in one class period. It also is being used for a phosphate analysis which, for the low levels of phosphorus often found in natural water, requires a sensitive instrument capable of accommodating long path lengths cells. Finally, it also is being used in a coordination chemistry project. ***

该项目的目标是完成一系列反映现代化学实践的普通化学实验室实验的开发。这两个学期的系列实验是一套多实验项目，让学生对现代仪器和化学的不同领域有一个早期的介绍。二极管阵列紫外/可见分光光度计被用于一个基于发现的有机光谱学项目，在这个项目中，32名学生在一堂课上记录了一些化合物的光谱。它也被用于磷酸盐分析，因为在天然水中经常发现的磷含量很低，需要一种能够容纳长路径长度细胞的灵敏仪器。最后，它也被用于一个配位化学项目。＊＊＊
