摘要
从最佳实验装置、反应异常现象分析、浓硫酸与铜的最佳用量3个方面对铜与浓硫酸反应进行了探究,并对普通高级中学高一《化学》课本中的浓硫酸与铜反应的演示实验装置进行了改进,取得了理想的实验效果.
The study focuses on the three aspects of the reaction: its experiment devices,abnormal reaction phenomena and the dosage of concentrated sulphuric acid and copper.Some changes are made in the demonstration experiment devices described in the textbook Chemistry of senior middle schools,and a satisfactory experiment result is obtained.
