摘要

摘要本文介绍了一名学生设计的通过镀锌铁钉锌涂层的电流置换从Pepto Bismol®片剂中提取的铋的一锅化学沉积。该实验依赖于一种易于获得且合理安全的方法和材料，在当前的新冠肺炎疫情期间，它已被用作高等教育学生（即初级和高级化学工程学生）的动手活动。它的简单性应该允许高中生使用。整个过程可以在30–45分钟内完成。

Homemade bismuth plating by galvanic displacement from bismuth subsalicylate tablets: a chemistry experiment for distance learning

Abstract This paper presents a student-designed one-pot electroless deposition of Bi extracted from a Pepto Bismol® tablet by galvanic displacement of the Zn coating of a galvanized iron nail. This experiment relies on a readily accessible and reasonably safe method and materials and it has been used during the present COVID pandemic as a hands-on activity with higher education students (i.e., Junior and Senior Chemical Engineering students). Its simplicity should allow its use with High School students as well. The entire procedure can be completed in 30–45 min.
