摘要

我们提出了一种由等摩尔（m）磷酸二氢钾和琥珀酸钠组成的缓冲混合物，作为研究酸碱平衡的有用参考点，弥补了目前 pH 5.5 和 pH 6.8 之间的差距。在 25 °C 时的 p(aH γ Cl) 是通过测量五种缓冲溶液的电动力测定的，其中 m 在 0.005 至 0.025 之间变化。得出了每种溶液的常规 pa H，并发现其与根据现有数据计算出的两种相关平衡的 pa H 非常一致。pa H 从 m=0.005 时的 6.251 到 m=0.025 时的 6.109 不等。该缓冲混合物已成功用于测定 2-硝基-4-氯苯酚和 2,6-二氯苯酚的解离常数。

Buffer Solutions of Potassium Dihydrogen Phosphate and Sodium Succinate at 25 °C.

A buffer mixture consisting of equal molalities (m) of potassium dihydrogen phosphate and sodium succinate is proposed as a useful reference point in the study of acid-base equilibria, bridging the present gap between pH 5.5 and pH 6.8. The p(a_H γ _Cl) at 25 °C has been determined by electromotive-force measurements for five buffer solutions in which m varied from 0.005 to 0.025. The conventional pa _H of each solution has been derived and found to be in good agreement with that calculated from existing data for the two equilibria concerned. The pa _H varies from 6.251 at m=0.005 to 6.109 at m= 0.025. The buffer mixture has been used successfully for the determination of the dissociation constants of 2-nitro-4-chlorophenol and 2,6-dichlorophenol.
