Calculating ksp

  1. Apr 24, 2012 #1
    Hey guys, I'm having trouble calculating the Ksp of this equation. I found an equation online but I don't understand it. I have Ksp=[Ca2+][IO3-]^2. I don't understnad how to use this formula? Thanks!

    The concentration of a saturated solution of PBI2 in water is 25ºC is 540 milligrams/liter. Calculate the Ksp for PbI2

    Seems to me like you are confusing everything with everything, plus some.

    Do you know how to write formula for a Ksp of a substance?
