Sodium chloride is added slowly to a solution that is 0.010 M in Cu*, Ag*, and Au*. Because solubility "rules" are generalizations, we don't use solubility rules when we have the specific Ksp data available. Instead, here, we can just use the Ksp value for CuCl which is 1.9 x 10-7, for AgCl is 1.6 x 10-10, and for AuCl is 2.0 × 10-13. Based on these specific Ksp values, which compound will precipitate first?

Calcium and magnesium ions can occur in our water supplies (e.g. through rocks and geological formations). A sample of tap water was tested and the calcium ion concentration was measured at 2.1E-5M and the magnesium ion concentration was measured at 1.2E-3M. If carbonate ion is added into the tap water, which ion will precipitate out of solution first? Explain your reasoning. The Ksp values of CaCo3 and MgCO3 are 5.0E-9 and 6.8E-6, respectively.
