10 mol/L = 0.01
AgCl <--> Ag+ + Cl-
0.01 0.01 0.01
Ksp = [Ag+] [Cl-]
= [0.01] [0.01]
= 1 x 10^-4
CaCl2 <--> Ca+ + 2Cl-
0.05 0.05. 0.05x2
AgCl <--> Ag+ + Cl-
0.05
x x x (ditambah)
x x 0.05 + x

Ksp AgCl = [Ag+] [Cl-]
10^-4 = [0.05 + x] [x] (Cat: Di sini x dianggap nilainya sangat kecil)
10^-4 = [0.05] [x]
x = 10^-4/5 x 10^-2
= 0.2 x 10^-2
= 2 x 10^-3 M atau 0.002 M
