Explain the solubility-product constants ksp

Reference no: EM13505648

The solubility-product constants, Ksp, at 25 Celcius for two compounds [iron(II) carbonate, FeCO_3, and cadmium(II) carbonate, CdCO_3 are given by the table

Substance K_p
FeCO_3 2.10* 10^{-11}
CdCO_3 1.80*10^{-14}

A solution of Na_2CO_3 is added dropwise to a solution that contains 1.02×10-2 M Fe^{2+} and 1.48×10-2 M Cd^{2+}. What concentration of {CO_3}^{2-} is needed to initiate precipitation? Neglect any volume changes during the addition.

In the solution from Part A, what will the concentration of {CO_3}^{2-} be when Fe^{2+} begins to precipitate?

Q: What will the concentration of Cd^{2+} be when Fe^{2+} begins to precipitate?
