7. How much Fe++ could be present in water containing 1 x 1e-02 M HCO3-
(bicarbonate) without causing the precipitation of FeCO3 (Ksp=10^(-10.7)) Hint: carbonate eq
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 ...
The solution explains how to utilize the solubility of FeCO3 to calculate the concentration of Fe++ without causing the precipitation in detail.
