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.
