在2019冠状病毒病大流行期间，南加州大学为普通化学课程的一部分创建并实施了一个家庭实验室项目。实验只使用安全的家庭用品，不使用特殊设备。这些实验活动跨越4周，重点关注第二学期化学实验室最后三分之一的概念，包括pH值、酸碱滴定、缓冲液、溶解度、相平衡和热力学。在这篇文章中，我们描述了实验室的设计和我们在这个实验中的经验，同时也对如何将类似的活动有效地整合到常规的普通化学课程中进行了评估。
During the COVID-19 pandemic, an at-home laboratory program was created and implemented for a section of the general chemistry course at the University of Southern California. The experiments were designed to only utilize safe household items and no special equipment. These laboratory activities, spanning over 4 weeks, focused on concepts usually covered in the final one-third of our second-semester chemistry laboratory, including pH, acid-base titrations, buffers, solubility, phase equilibria, and thermodynamics. In this article, we describe the design of the laboratories and our experience with this experiment, while also providing an assessment on how similar activities could be integrated profitably into a regular general chemistry course.
