一、电化学知识在高考中的地位原电池、电解池原理及其应用涉及化学理论、元素化合物知识以及化工生产应用,是高考必考的重点内容,电极反应式的书写是电化学考查的重点和难点。纵观近几年全国卷高考试题,对原电池、电解池的考查从不间断,题目呈现方式主要以选择题和综合考查的传统题型为主,其中应用原电池、电解池的工作原理分析新型电池、电极方程式的书写是高考热点。如2010年全国卷Ⅰ选
First, the electrochemical knowledge in the college entrance examination The status of primary batteries, electrolysis cell theory and its application involves chemical theory, chemical compounds and chemical production applications, is the key content of the college entrance examination, the reaction of the electrode is the focus of electrochemical tests And difficult. Throughout the national examination in recent years, the entrance exam, the original battery, electrolysis cell test uninterrupted, the problem presented mainly in multiple choice and comprehensive examination of the traditional type of questions, including the use of primary batteries, electrolysis cell working principle analysis New battery, the electrode equation writing is hot college entrance examination. Such as the 2010 National Volume Ⅰ election
