过氧化钠是钠的重要化合物,也是高考命题的热点,特别是Na2O2与H2O、CO2的反应及计算,并且可以衍生到有机物的燃烧及其产物与Na2O2反应的考查.现对教材中Na2O2与H2O、CO2的反应进行详细分析、总结规律,并拓展到有机物完全燃烧后所得产物与Na2O2反应后固体质量及气体体积的变化.一、Na2O2与H2O、CO2反应的分析过氧化钠与水反应生成氢氧化钠和氧气:
Sodium peroxide is an important compound of sodium, which is also a hot spot of the college entrance examination proposition, especially the reaction and calculation of Na2O2 with H2O, CO2, and can be derived from the combustion of organic matter and the reaction of the product with Na2O2. Now Na2O2 and H2O in teaching materials. The reaction of CO2 and CO2 is analyzed in detail, and the rules are summarized, and the change of solid mass and gas volume after reaction of Na2O2 with the product obtained after the complete combustion of organic matter is developed. I. Analysis of the reaction of Na2O2 with H2O, CO2 The reaction between sodium peroxide and water generates hydrogen Sodium oxide and oxygen:
