What scientific concept do you need to know in order to solve this problem? Since the compounds are ionic compounds, they form ions when dissociating in water. CaSO4. c) Ni(OH)2          Ksp = 6.0 x 10-16 Sodium is in Group 1A so it’s charge is +1: Notice that there is a common ion present, SO42–. Remember that solids are ignored in the ICE table. Calcium sulfate [NF] Calcium sulfate, 99%. Problem: The Ksp of CaSO4 is 4.93 x 10-5. 2 Ca2+ and SO42-for solution 2 are less than for solution 1 because the ionic strength of solution 2 is greater than the ionic strength of solution 1, and as a result [Ca2+] and [SO 4 2-] must be larger in solution 2 for both solutions to satisfy the K sp … The dissociation of CaSO4 and Na2SO4 in water are as follows: The sulfate ion, SO42–, has a charge of –2. We can construct an ICE table for the dissociation of CaSO4. Services, Solubility Equilibrium: Using a Solubility Constant (Ksp) in Calculations, Working Scholars® Bringing Tuition-Free College to the Community. You can view video lessons to learn Ksp.
