    Please see the detailed solutoin in the attached file.

    In the first place we have the balanced equation:
    FeCO3 <--> Fe2+ + CO32- (1)

    Then we must look at the ...

    Solution Summary

    The solution explains how to utilize the solubility of FeCO3 to calculate the concentration of Fe++ without causing the precipitation in detail.
