A solution contains ba2 50 times 10-5 m zn2 20 times 10-7


A solution contains [Ba2+] = 5.0 × 10^-5 M, [Zn2+] = 2.0 × 10^-7 M, and [Ag+] = 3.0 × 10^-5 M. Sodium oxalate (Na2C2O4) is slowly added so that the following salts are formed. 

Salt:   BaC2O4               ZnC2O4                 Ag2C2O4 

Ksp:  1.5 × 10^-8          1.35 × 10^-9           1.1 × 10^-11

What is the order of the cations that would precipitate with the addition of C2O42-? (Hint: The cation that requires the lowest molarity of C2O42- to precipitate would precipitate first.)
