用P~H电位法研究了在0.1MKNO_3水溶液中(30.0±0.1℃)的银(Ⅰ)—NH_3—NS(亚氨基二磺酸钾)的加合反应,并测得了这个加合反应的平衡常数K_(111),混合型络合物积累生成常数β_(111),讨论了P~H滴定曲线,混合型络合物的稳定性以及实际NS镀银液中各种络离子随溶液P~H的改变而变化的情况.
Addition reaction of silver (Ⅰ) -NH 3 -NS (potassium iminodisulfonate) in 0.1M KNO 3 aqueous solution (30.0 ± 0.1 ℃) was studied by P ~ H potential method and the balance of this addition reaction was measured The constants K_ (111) and β_ (111) of the mixed complex accumulate and the P ~ H titration curve, the stability of the mixed complex and the effect of various complex ions in the NS plating solution with the solution P ~ H changes and changes in the situation.
