摘　　要：深入讨论了pH滴定法滴定极弱酸碱的原理、方法和应用,对10种不同极弱酸碱进行了广泛的测定,测定结果相对误差一般在0.2％左右,相对标准偏差在0.2％左右,达到化学分析要求。pH滴定法具有简便、价廉、快速和通用的优点,为直接滴定极弱酸碱和化学分析仪器化开辟了新的途径。Abstract The principles, method, and application of the pH-titration of very weak acids and bases are discussed. Ten kinds of samples are measured experimentally, yielding the re- sult with relative errors of about 0. 2% and the relative standard deviations of about 0. 3% which meet the requirement of general chemical analysis. The method is simple, cheap and qick.and thus is of potential for use.
