（12分）（1）已知在25℃时，醋酸、碳酸和亚硫酸的电离平衡常数分别为：

醋酸     K_i = 1.75×10^－5

碳酸     K_{i 1}= 4.30×10^－7      K_{i 2} = 5.61×10^－11

亚硫酸   K_{i 1}= 1.54×10^－2      K_{i 2} = 1.02×10^－7    

写出碳酸的第一级电离平衡常数表达式：K_i = _     __

在相同条件下，试比较H₂CO₃、HCO₃^－和HSO₃^－的酸性最强的是     

③ 若保持温度不变，在醋酸溶液中加入少量盐酸，下列量会变小的是     （填序号）

A. c(CH₃COO^－)     B. c(H⁺)      C. _w醋酸电离平衡常数     D. 醋酸的电离度 

（2）一定温度下的难溶电解质A_mB_n在水溶液中达到沉淀溶解平衡时，其平衡常数

Ksp＝c^m(A^n＋)×cⁿ(B^m－)，称为难溶电解质的离子积。在25℃时，AgCl的白色悬浊液中，依次加入等浓度的KI溶液和Na₂S溶液，观察到的现象是先出现黄色沉淀，最后生成黑色沉淀。

下列叙述不正确的是                           

A．溶度积小的沉淀可以转化为溶度积更小的沉淀

B．若先加入Na₂S溶液，再加入KCl溶液，则无白色沉淀产生

C．25℃时，饱和AgCl、AgI、Ag₂S溶液中所含Ag^＋的浓度相同

D．25℃时，AgCl固体在等物质的量浓度的NaCl、CaCl₂溶液中的溶度积相同
