Many students enroll in college general chemistry with an interest in a medical career. In those (and alternative) careers, they will need to make critical decisions about data and how that data are acquired. A significant portion of introductory lab experiments are, in principle, but not necessarily in practice, devoted to understanding how chemical information is gained and how it is deemed reliable. Here we report on a laboratory experiment that is presented as a guided inquiry investigation grounded in the history of science and the link between early medicine and quantitative data. Oak gall extract is used to quantitatively determine the amount of iron present in a water sample using UV–vis absorbance. In this experiment, students are introduced to the Beer–Lambert law, calibration curves, and the reading of UV–vis spectra

医师作为第一位分析化学家：坚果提取物测定铁离子（Fe ²⁺）浓度

许多学生对医学职业感兴趣，因此报名参加了大学的普通化学课程。在那些（和其他）职业中，他们将需要做出关于数据以及如何获取数据的关键决策。原则上但不一定在实践中，很大一部分入门实验室实验专用于了解如何获取化学信息以及如何认为其可靠。在这里，我们报告了一项实验室实验，该实验作为指导性探究调查而提出，该调查以科学史以及早期医学和定量数据之间的联系为基础。橡木胆提取物用于通过UV-vis吸光度定量测定水样品中的铁含量。在该实验中，向学生介绍了比尔-兰伯特定律，校准曲线以及紫外线-可见光谱的读数
