铜盐和铅盐是中学化学实验的常用药品,现介绍用空气氧化的简易制法: 硫酸铜铜在与空气接触的条件下能与硫酸起如下反应: Cu+1/2O_2+H_2SO_4=CuSO_4+H_2O 工业上把铜和稀H_2SO_4加热到70-80℃,通入空气,生产CuSO_4·5H_2O。在常温下,反应速度较慢。把从废导线中取得的铜丝及2M稀H_2SO_4溶液,放入大烧杯或大磁碗里,酸液的高度约为铜丝 Copper salts and lead salts are commonly used in chemical experiments in middle schools. The simple method of air oxidation is now introduced: Copper copper sulphate reacts with sulphuric acid in the following conditions: Cu+1/2O_2+H_2SO_4=CuSO_4+ H2O Industrially, copper and dilute H_2SO_4 are heated to 70-80°C, and air is introduced to produce CuSO_4·5H_2O. At room temperature, the reaction rate is slower. The copper wire obtained from the scrap wire and the 2M dilute H 2 SO 4 solution are put into a large beaker or a large magnetic bowl. The height of the acid is about copper wire.
