    Hi everyone!
    this question from topscore is really bugging me. I've tried to look up the correct answer and understand why it is right, but I'm still confused. Here's the question:

    What is the expression for the solubility product constant, Ksp, for BaCl2?
    Topscore says the answer is [Ba+2][Cl-2], but isn't Cl-1?? I don't get it...please help!

    it's most definately a misprint/typo :

    It should be [Ba+2][Cl-]^2

    Yes certainly a typo, it is correct but the 2 should have been outside the bracket representing the number of atoms of Cl in the molecule BaCl2 which is 2. Good question. These study references have mistakes every now and again so not to worry, the fact that you recognized it shows you know your stuff!

    The typo occurred in ver 07.15 as answer A instead of answer C. This has been corrected and any question fixes are published on our support page at Good luck!
