铜与稀硝酸反应装置的改进与创新

Reaction Device for Copper and Dilute Nitric Acid Improvement and Innovation

人教版高中化学必修1第四章铜与稀硝酸反应是高中化学的一个重要实验。在铜与稀硝酸反应的实验中如何呈现产生的气体是无色NO而非红棕色气体NO2是实验的关键,但是在实验中NO很容易转化为NO2,因此对铜与稀硝酸反应装置进行了改进与创新。

People’s Education Edition High School Chemistry Repair 1 Chapter 4 Copper and Dilute Nitrite Reaction is an important experiment in high school chemistry. How to presented the generated gas in the experiment of copper and dilute nitric acid is a colorless NO rather than red brown gas NO2 is the key to experiment,but NO in the experiment is easily converted to NO2,so this paper is copper and dilute nitric acid reactive device Improvement.
