高中化学必修二ppt | 03 硫酸
前言：以下是本人林含键课堂教学课件分享（前面已分享了必修二2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！
这一节是学习硫酸，稀硫酸在初中已接触过，回顾酸的通性，之后重点认识浓硫酸的性质，包括物理性质、吸水性、脱水性和强氧化性。
回顾前面学习的二氧化硫的内容，为后面铺垫。
回顾稀硫酸的电离方程式和酸的通性。
引用初中课本中浓硫酸的内容，理解浓硫酸的腐蚀性。

脱水性在初中也有介绍，这里补充观看“黑面包”实验视频。
小结脱水性，也是炭化的过程。对比吸水性和脱水性。
强氧化性是重难点，这个实验需要剖析清楚。从现象到实验的细节，再到方程式的书写。

从反应方程式中变价情况分析浓硫酸的性质，在反应中体现氧化性和酸性。同时，留意浓变稀的问题。
浓硫酸与非金属的反应，相对比较简单。同时，学习检验混合物中水的实验设计，对应一开始的那道题。
补充浓硫酸与某些还原性物质反应。
