电化学知识是中学无机化学理论非常重要的组成部分,也是近年高考题的必考内容,重现率高,所占比率大．高考电化学中的计算类问题主要包括以下几种类型:两极产物的定量计算、溶液pH的计算、相对原子质量和阿伏加德罗常数测定的计算、某元素的化合价或确定物质的化学式等,解决上述问题的常用方法有守恒法、总反应式法、关系式法等．
Electrochemical knowledge is a very important part of middle school’s inorganic chemistry theory. It is also a must-examination content for college entrance examination in recent years. The rate of reproduction is high and the proportion is high. The computational problems in the college entrance examination electrochemistry mainly include the following types: quantitative calculation of bipolar products, calculation of solution pH, calculation of relative atomic mass and Avogadro constant, valence of an element, or chemical formula of a defined substance The commonly used methods to solve the above problems are conservative method, total reactive method, relational method, etc.
