1.本文証明碱金属离子M+与酒石酸(H2L)生成ML-和MHL两种絡合物(其稳定常数見表7)。2.以四甲基氫氧化銨滴定酒石酸,在25°和μ=0.2的条件下,求得酒石酸在水溶液和不同浓度的二氧六环水溶液中的pK1和pK2(表5)。

The existence of tartrate and acid tartrate complexes of alkaline metal ions in aqueous solutions have been demonstrated by potentiometric measurements with a glass electrode. This result necessitates the revision of the previously determined values of the ionization constants of tartaric acid. Table 1 and 2 summarize the results obtained in the present investigation together with those of Cannan and Kibrick[1].
