摘要
借助手持技术,利用电压传感器和pH传感器测定不同酸碱性环境下金属铁发生电化学腐蚀的模拟原电池电压变化情况,探究金属铁发生析氢腐蚀和吸氧腐蚀对应的pH范围,帮助学生深入理解铁的电化学腐蚀原理,感受化学定量实验的魅力。
With the help of handheld technology,the voltage change of iron electrochemical corrosion in different acid-base environments is measured by voltage sensor and pH sensor,and the pH range corresponding to hydrogen evolution corrosion and oxygen absorption corrosion of iron is explored to help students understand the principle of iron electrochemical corrosion and feel the charm of chemical quantitative experiment.
