铜与浓、稀硝酸的反应实验改进

Experimental Improvement of the Reaction Between Copper with Thick,Thin Nitric Acid

浓、稀硝酸氧化性不同,通过进行铜与浓、稀硝酸的反应实验现象及反应产物的对比实验,加强学生对不同浓度的硝酸氧化性不同的理解,同时增强学生的环保意识。

The oxidation of thick,thin nitric acid is different. Through the experiment of the reaction between copper with thick,thin nitric acid. The reaction experiment phenomenon and the reaction products were compared, which enhance students＇ understanding of different oxidation of different concentrations of nitric acid. At the same time, enhance the students＇ awareness of environmental protection.
