Question:

You slowly add ammonia, NH3, to 1.00 L of water containing 5.00 g of solid nickel(II) iodate, Ni(IO3)2. How much ammonia (in moles) would you have to add to just dissolve the nickel(II) iodate? What would be the molar concentration of ammonia in the solution at that point? Ksp for nickel iodate is 1.4 × 10-8.
