1、名师精编优秀教案【新编精品】人教化学必修一2.2 离子反应导学案（第1 课时）【学习目标】1.知道电解质、非电解质、电离的概念；2.能列举一些典型的电解质，知道酸、碱、盐是电解质；3.知道强电解质、弱电解质的概念；4.理解溶液导电的原理；5.能书写电解质的电离方程式。【练一练】下 列哪些物质能导电？铁氯化钠晶体盐酸铜氯化钠溶液稀硫酸锌硝酸钾晶体烧碱固体铝硝酸钾溶液烧碱溶液金葡萄糖溶液硫酸钡结论与原因：金属单质 (填能、不能)导电，原因：；氯化钠固体及酒精 (填能、不能)导电，原因：；表格中的氯化钠晶体、硝酸钾晶体、烧碱固体、硫酸钡有什么方法能使其导电？为什么？葡萄糖固体熔化后能导电吗？为什么？
2、名师精编优秀教案下列叙述正确的是；A.氯化钠溶液能导电，所以氯化钠溶液是电解质B.固体氯化钠不导电，但氯化钠是电解质C.氯化氢水溶液能导电，所以氯化氢是电解质D.三氧化硫溶于水能导电，所以三氧化硫是电解质E.铜能导电，所以是电解质F.BaSO4的水溶液不能导电，所以BaSO4是非电解质G.氨气溶于水能导电，所以氨气是电解质1.(自学、归纳)归纳总结，完成下表：电解质非电解质定义本质结构特点共同点举例2.(讨论、交流)查阅资料，什么是强电解质？什么是弱电解质？常见的强电解质与弱电解质分别有哪些物质？3.(思考、讨论)写出下列物质的电离方程式。H2SO4：Ba(OH)2：MgCl2：CH3COOH
