能源问题已成为当今社会热点。在近几年的各地高考试题中,以能源问题切入,结合新能源开发及新型电池等相关电化学知识的考查无疑是一种很好的方式,充分体现了高中化学课程“基础性、应用性、时代性”的特征。如电化学原理,既是高中化学的重点和难点,更是一个长考不衰的频点、热点。现就近几年高考中电化学知识的命题视角和特点谈几点粗浅的看法。难求全面,权作引玉之砖。一、注重基础,考查电化学基本原理1.涉考内容电化学部分的基础知识包括:原电池、电解池的判
The issue of energy has become a hot spot in society today. In recent years, college entrance examination examination questions in various places, cut into the energy issue, combined with new energy development and new battery-related electrochemical knowledge of the test is undoubtedly a good way to fully reflect the high school chemistry curriculum “basic, application Sexual, Periodical ”features. Such as electrochemical principles, both high school chemistry is the focus and difficulty, but also a long test not bad frequency, hot spots. Now in recent years, college entrance examination electrochemical knowledge proposition perspective and characteristics to talk about a few superficial views. Hard to find comprehensive, the right to lead the brick. First, pay attention to the foundation, examining the basic principles of electrochemical 1. The contents of the electrochemical part of the basic knowledge includes: the original battery, electrolytic cell sentence
