You have a 250ml solution of 0.13M calcium iodate. How many grams of potassium iodate need to be added to the solution to begin to precipitate calcium iodate? The solubility product constant for calcium iodate is6.47 *10^-6.
B) you have a 250ml solution of 0.13 M calcium iodate. How many total grams need to be added to the solution until it is saturated in potassium iodate? The ksp for potassium Iodate is 0.183.
pls help me with this problem

Neither problem makes any sense to me. With Ksp = 6.47E-6, the solubility of Ca(IO3)2 is 0.0117 in a saturated solution. Therefore, you can't have a 0.13M solution. You don't need to add any KIO3; Ca(IO3)2 is already pptd.
