What is the minimum concentration?
Determine the minimum concentration of the precipitating agent on the right to cause precipitation of the cation from the solution on the left.

8.0 x 10^-2 CaI2, K2SO4

1.5 x 10^-3 AgNO3, RbCl

The Ksp values for both are Ksp = 2.4*10-6 for CaSO4, and Ksp = 1.8*10-10 for AgCl.
