质量守恒、能量守恒、电荷守恒是自然界中存在的最基本的守恒规律,也是化学研究的重点内容之一。从历年的高考来看,应用电荷守恒观点解题的考查几乎每年必有,所考查的内容主要有:(1)电荷守恒观点在氧化还原反应中的体现;(2)电荷守恒观点在 Conservation of mass, conservation of energy and conservation of charge are the most basic laws of conservation in nature and are also one of the key points in chemical research. From the calendar year college entrance examination point of view, the application of conservation of electricity point of view to solve the problem almost every year, the contents of the examination are: (1) the charge conservation point of view in the redox reaction embodied; (2) the charge conservation point of view
