通过2014年的高考试题可以看出,电化学的命题点侧重于考查大家对教材基础知识的综合应用能力,题型既源于教材,又高于教材.因此,我们在复习时,要明确教材的基础知识准确把握电化学的高考命题点.一、原电池原理的考查例1锂锰电池的体积小,性能优良,是常用的一次电池.该电池反应原理如图1所示,其中电解质Li Cl O4溶于混合有机溶剂中,Li+通过电解质迁移入MnO2晶格中,生成LiMnO2.回
Through the college entrance examination 2014 questions can be seen, the electrochemical proposition point focused on examining the comprehensive application of basic knowledge of teaching materials ability, the question is derived from the textbook, but also higher than textbooks.Therefore, we review the textbook to be clear The basic knowledge of the accurate grasp of the electrochemical college entrance examination proposition point. A test of the original battery principle Example 1 lithium manganese battery, small size, excellent performance, is a common battery. The battery reaction principle shown in Figure 1, in which electrolyte Li Cl O4 dissolved in a mixed organic solvent, Li + through the electrolyte into the MnO2 lattice, generating LiMnO2 back
