本书的第一部分（实际测量中的影响因素）着重介绍传感器和构 成 pH 测量系统的其他元件。这一部分在介绍重要信息的同时配以 故障排除示意图，以确保 pH 电极能够长时间正确运行。第二部分侧 重于应用，其中以实验室和工业为例介绍了针对不同测量需求的解 决方案。最后一部分为理论部分，其中介绍了 pH 测量的基本原理， 并对第一部分中介绍的信息作进一步解释。
图 1 酸碱相互反应便生成了水
如果一种物质的分子解离释放出氢离子（质子），那么我们将这种物 质称为酸性物质，溶液呈酸性。最耳熟能详的酸性物质为盐酸、硫酸 和醋酸（即：醋）。醋酸的解离图如下： CH3COOH + H2O ⇌ CH3COO– + H3O+
图 2 醋酸解离
并非所有的酸都具有相同的强度。究竟一种物质的酸性程度如何， 可通过溶液中的氢离子总数判定。于是，将 pH 值定义为氢离子浓度 的 负 对 数。（ 更 准 确 地 说，是 通 过 氢 离 子 的 活度 来 判 定）。请 参 阅“5.2浓度与活度之间关系”（第 69 页）了解关于氢离子活度的更多 详情）
NH3 + H2O ⇌ NH4+ + OH–
图 5 氨与水反应
水溶液 pH 值的整个坐标包括酸性与碱性范围。pH 值可在 0 与 14 之间变化，其中 0 至 7 之间的 pH 值为酸性，7 至 14 之间的 pH 值为碱性。当 pH 值等于 7 时为中性。
