Spectrophotometry in the Freshman Chemistry Laboratory

分光计能激发化学一年级学生的兴趣。它是一种强大的分析工具，大多数学生认为它是实习化学家使用的最先进的工具。这个项目包括在每个实验站放置一台分光计，以便每对实验学生都有自己的仪器。这些实验包括发现光的本质，验证溶液浓度和光学规律，对从阿司匹林到配位络合物的各种学生准备的化合物进行光谱分析，以及评估平衡常数。许多计划的活动与其他实验或技能密切相关，包括读取模拟仪表显示、绘图技术、溶液制备、合成、容量滴定、离子交换层析和计算机接口。光谱学可以作为学生在实验室课程中的数学和化学概念的重点。该机构正在将这笔赠款与同等数额的资金相匹配。

The spectrometer can spark the interest of the freshman chemistry student. It is a powerful analytical instrument that most students identify as a state-of-the-art tool used by practicing chemists. This project involves placing a spectrometer at each lab station so that each pair of lab students have their own instrument. The experiments include the discovery of the nature of light, verification of the law governing solution concentration and optical, spectral analysis of various student prepared compounds ranging from aspirin to coordination complexes, and evaluation of an equilibrium constant. Many of the planned activities are closely connected to other experiments or skills that include reading analog meter displays, graphing techniques, solution preparation, synthesis, volumetric titration, ion exchange chromatography, and computer interfacing. Spectrometry can serve as a focal point of mathematical and chemical concepts for students in laboratory courses. The institution is matching the grant with an equal amount of funds.
