A solution contains 0.20 M CrO 4 2- , 0.10 M CO 3 2- , and 0.010 M Cl - . If solid AgNO3 is added slowly to the solution without changing the total volume of the solution, in what order will the precipitates, Ag2CrO4, Ag2CO3, and AgCl, form?
a. 1st: Ag2CO3 2nd: Ag 2CrO4 3rd: AgCl
b. 1st: Ag2CrO4 2nd: Ag 2CO3 3rd: AgCl
c. 1st: AgCl 2nd: Ag 2CrO4 3rd: Ag 2CO3
d. 1st: AgCl 2nd: Ag 2CO3 3rd: Ag 2CrO4
e. 1st: Ag2CO3 2nd: AgCl 3rd: Ag 2CrO4
