  1. 5. 100 mL 0.0300 mol / L KCl溶液中加入0.3400 g固体硝酸银。求溶液中的pCl及pAg。

  2. 6 将0.1159 mol / L AgNO3溶液30.00 mL加入含有氯化物试样0.1155 g的溶液中，然后用3.16 mL 0.1033 mol / L NH4SCN溶液滴定过量的AgNO3。计算式样中氯的百分含量。

  3. 7. 称取一定量的约含52% NaCl和44% KCl的试样。将试样溶于水后，加入0.1128 mol / L AgNO3溶液30.00。过量的AgNO3需用10.00 mL标准NH4SCN溶液滴定。已知1.00 mL NH4SCN相当于1.15 mL AgNO3。应称取试样多少克？
