已知25℃时，AgI饱和溶液中c(Ag+)为1.22×10－8 mol/L，AgCl的饱和溶液中c(Ag+)为 1.25×10－5 mol/L。若在5mL含有KCl和KI各为0.01mol/L的溶液中，加入8mL0.01mol/LAgNO3 溶液，这时溶液中所含溶质的离子浓度大小关系正确的是 [ ]
A．c (K+)＞c (NO3－) ＞c (Ag+) = c (Cl－) + c (I－)
B．c (K+)＞c (NO3－) ＞c (Ag+) ＞c (Cl－)＞c (I－)
C．c (NO3－)＞c (K+)＞c (Ag+) ＞c (Cl－)＞c (I－)
D．c (K+)＞c (NO3－) ＞c (Cl－) ＞c (Ag+)＞c (I－)
答案
答案：D
