摘要
在25±0.2℃及 I=O.1mol·L^(-1)KNO_3存在下,用 pH 法分别测定了在80%(V/V)二甲亚砜混合溶剂中水的离子积常数、芬布芬的离解常数以及芬布芬与二价的铜、钴、镍、锌四种金属离子形成二元配合物的稳定常数.结果表明,这四种配合物的逐级稳定常数间均符合一般规律,且与金属离子的 Irving-Williams次序一致.
The ion product constant of water,the protonation constant ofFenbufen and stability constants of the complex compounds formed from ligandwith copper(Ⅱ),nickel(Ⅱ),cobalt(Ⅱ)and zinc(Ⅱ)have been determined bypH method at 25±0.2℃,Ⅰ=0.1mol.L^(-1)(KNO)_3)in mixed solvents〔80%(V/V)DMSO〕.The results showed that the successive stability constants of thesecomplexes accord with the general law and the Irving-Williams order of metalions.
