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.

COVID-19 大流行期间在家庭普通化学实验室进行实验

在 COVID-19 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计划。实验仅使用安全的家居用品，不使用特殊设备。这些实验室活动持续 4 周多，重点关注通常在第二学期化学实验室最后三分之一时间中涵盖的概念，包括 pH、酸碱滴定、缓冲液、溶解度、相平衡和热力学。在本文中，我们描述了实验室的设计以及我们在该实验中的经验，同时还对如何将类似的活动有利地整合到常规普通化学课程中进行了评估。
