A solution is 0.1 M in each KCl, KBr and K­2 CrO4 to this solution solid AgNO3 is gradually added. Assume there is no change in the volume of the solution given:
Ksp (AgCl) = 1.7×10−10
Ksp (AgBr) = 5.0×10−13 and Ksp (K2CrO4)=1.9×10−12
The concentration of first ion when the second ion starts precipitating is about:
