摘要
用pH-电位滴定法测定了在25℃,离子强度I=0.10(KNO_3)条件下,镉(Ⅱ)、锌(Ⅱ)与水杨酸、5-溴水杨酸、5-磺基水杨酸和3,5-二硝基水杨酸在水溶液中形成二元配合物的1,2级稳定常数。结果表明配合物的稳定性与取代水杨酸配体的碱性强度之间存在直线自由能关系。
The first and sencond order equilibrium constants of binary coordination compounds of Cd (Ⅱ) and Zn (Ⅱ) with salicylic acid and its derivatives were determinated. A linear free energy relationship between the stability of coordination compounds and the basicity of salicylic acids was gived and discussed.
