一、氮元素知识链二、氮元素间的氧化还原反应认识和理解1.两种氮元素的氧化还原反应类型①归中反应实验室常用饱和NaNO2与NH4Cl溶液加热反应制取氮气硝酸工业常用碱液吸收氮的氧化物NO+NO2+2NaOH=2NaNO2+H2O 目前治理NO、NO2的一种新方法是在一定温度、有催化剂存在的条件下,用氨催化还原法 First, the nitrogen knowledge chain Second, the understanding and understanding of the redox reaction between nitrogen elements 1. Two types of nitrogen redox reaction type 1 Guizhong reaction laboratory commonly used saturated NaNO2 and NH4Cl solution heating reaction for the production of nitrogen nitric acid industry commonly used alkali Nitrogen oxides absorbed by liquids NO+NO2+2NaOH=2NaNO2+H2O A new method for the treatment of NO and NO2 is to use ammonia-catalyzed reduction at a certain temperature and in the presence of a catalyst.
