Answer» A solution is $0.1 M$ in each $K C l, K B r$ and $K_{2} C r O_{4}$ . To this solution solid $A g N O_{3}$ is gradually added. Assume no change in the volume of the solution. Given: $K_{s p} (A g C l) = 1.7 \times 10^{- 10}$ $K_{s p} (A g B r) = 5 \times 10^{- 13}$ and $K_{s p} (A g_{2} C r O_{4}) = 1.9 \times 10^{- 12}$ The concentration of first ion when the second ion starts precipitating is:
