应用电极反应分析有关电解问题赵李增（河北玉田一中０６４１００）电解的原理及其应用是电化学的重要内容之一。其中用惰性电极电解时溶液的ＰＨ值的变化及电解总方程式的写法，电解后溶液ＰＨ值的计算两大部分内容是高考的热点，也是学生学习的难点，但如果应用电极反应... Application of electrode reaction analysis on electrolytic problems Zhao Lizeng (Hebei Yutian No. 064100) The principle and application of electrolysis is one of the important aspects of electrochemistry. Among them, the change of the pH value of the solution and the writing of the electrolysis equation, the calculation of the PH value of the solution after electrolysis using the inert electrode are the hot spots of the college entrance examination, and also the difficulties for the students to learn, but if the electrode reaction is applied...
