摘　　要：浓硝酸和铜反应的溶液为草绿色,说法较多,还存在疑问。通过大量的实验,认为主要是NO2和水反应生成的亚硝酸,再结合铜离子生成铜的亚硝酸化合物,使溶液呈绿色。The reaction solution of concentrated nitric acid and copper is grass green, there are various interpretations, the experiment is doubtful. Through a lot of experiments, results showed that it was mainly the nitrous acid produced by the reaction of NO2 and water, and then combined the copper ion to form the nitrite compound of copper, which made the solution green.

关 键 词：浓硝酸 铜 铜的亚硝酸化合物 绿色溶液
