1、离子反应第 1 课时教学目标1.能从宏观与微观相结合的角度对物质进行分类，理解电解质、非电解质的概念，了解常见的电解质。2.通过分析、推理等方法认识电解质的电离及电离条件，建立书写电离方程式的认知模型，加深对酸、碱、盐的认识。教学重难点【教学重点】电解质的概念，电离方程式的书写。【教学难点】电解质和非电解质的判断。教学过程一、导入新课用电安全规范中要求：不要用湿手去接触电源开关、插座或其他电器设备。这是为什么呢？二、讲授新课（一）物质的导电性试验【复习提问】纯净的蒸馏水导电吗？【学生】不导电。【实验演示】NaCl 固体导电吗？探究结论：不导电。【实验演示】NaCl 溶液导电吗？探究结论：导电。
2、（将蒸馏水加入装有NaCl 固体的烧杯中，得到NaCl 溶液，灯泡发光，说明 NaCl 溶液能导电）【提问】KNO3固体导电吗？【学生】类比NaCl 固体，不导电。【提问】熔融态KNO3导电吗？【学生】导电。【总结】物质纯水NaCl 固体NaCl 水溶液熔融态 KNO3精品w o r d 可编辑资料-第 1 页，共 13 页-能否导电不能不能能能【设疑】为什么NaCl 固体不导电，NaCl 水溶液导电？【投影】氯化钠在水中的溶解和电离的示意图【讲述】在NaCl 固体中含有带正电荷的Na+和带负电荷的Cl-，由于带相反电荷的离子间的相互作用，Na+和 Cl-按一定规则紧密地排列着。这些离子不能自
3、由移动，因而氯化钠的固体不能导电。当 NaCl 溶于水时，水分子的作用减弱了Na+和 Cl-之间的相互作用，使 NaCl 固体离解成能够自由移动的Na+和 Cl-，因而 NaCl 溶液能够导电。【知识迁移】同理，同学们再来解释一下熔融态KNO3导电的原因。【回答】KNO3在熔融态产生了可以自由移动的离子。（二）相关概念【板书】一、电解质和非电解质1概念(1)电解质：在水溶液里或熔融状态下能够导电的化合物。(2)非电解质：在水溶液里和熔融状态下均不能导电的化合物。2常见物质类别精品w o r d 可编辑资料-第 2 页，共 13 页-文档编码:CA8I9I3U2H10 HR9Q2X8I6J4 Z
