Determine the solubility of FeS at 25 degrees Celsius

  • Chemistry -

    FeS ==> Fe^2+ + S^2-

    Ksp = (Fe^2+)(S^=)
    Look up the Ksp for FeS, set up an ICE chart, substitute into the Ksp expression and solve for the solubility.

  • Chemistry -

    What is an ICE chart?

  • Chemistry -

    If we let x stand for the solubility of FeS, then x is the concn of iron(II) and x is the concn of S^2-.
    ................FeS ==> Fe^2+ + S^2-
    initial...................0......0
    change....................x.......x
    equil.....................x.......x

    I stands for initial
    C stands for change
    E stands for equilibrium.
    I have set one up above for you.
    So you substitute x for (Fe^2+) and x for (S^2-), and whatever you find in your text for Ksp FeS, and solve for x.
