高中化学必修二ppt | 09 铵根离子的检验、氨气的制备和硝酸
前言：以下是本人林含键课堂教学课件分享（前面已分享了必修二8个课件和必修一55个课时的课件合集【高中化学必修一ppt】55 期末模拟卷讲评）。课件获取方式请看文末指引（禁止未授权的二次传播或商用，原创不易，感谢理解！
这一节延续上节课的内容，介绍铵盐与碱反应的两个重要的应用，一是铵根离子的检验，二是实验室制氨气。之后再学习硝酸的性质，包括不稳定性和强氧化性。
课前回顾练习
铵盐与碱的反应实验。

了解其他的制法。
练习，强化对制取氨气的理解。
硝酸的物理性质和化学性质中的不稳定性，影响了硝酸的保存方法。掌握硝酸的分解反应。
硝酸的强氧化性是重点内容。与铜反应的现象，离子方程式和对应的产物，都是需要深入理解的内容。
