摘要： 在化学合成、分析测定实验过程中，溶液pH是影响实验结果的重要因素之一。熟练掌握测定溶液pH的方法，是高校化学类专业学生必须掌握的基本实验技能。本文主要介绍了pH试纸及其他试纸和pH计的工作原理及使用方法，并对测定过程中的具体操作提出规范建议。

关键词: pH试纸, pH计, 操作规范

Abstract: During the process of chemical synthesis and analytical determination, the pH of the solution is one of the important factors affecting the experimental results. Mastering the method of measuring the pH of a solution proficiently is a basic experimental skill that students majoring in chemistry in colleges and universities must possess. This paper introduces the types, working principles, and usage methods of pH test papers and pH meters, and puts forward standardized suggestions for the specific operations during the measurement process.

Key words: pH Indicator paper, pH Meter, Standard operating procedure
