1.本文証明碱金属离子M~+与酒石酸(H_2L)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pK_1和pK_2(表5)。
1. This paper proves that the alkali metal ions M ~ + and tartaric acid (H_2L) produce two complexes of ML ~ - and MHL (the stability constants in Table 7). 2. Titration of tartaric acid with tetramethylammonium hydroxide and determination of pK_1 and pK_2 of tartaric acid in aqueous solution and different concentrations of aqueous dioxane solution at 25 ° and μ = 0.2 (Table 5).
