- calculate the solubility of ca3(po4)2 in water ksp = 2.07 x 10-331) Listen The Ksp value for calcium sulfate [CaSO4] is 2.40 X 10-5 and a professor made 1825 mL of a CaSO4(ag) solution but then one of his graduate student accidentally poured in a 0.125 M solution of calcium phosphate [Ca3(PO4)2] solution. You may ignore the additional volume coming from the Cag(PO4)2 solution to make the calculation simpler. Now that you have calculated the new equilibrium constant (K) with this common ion effect then which way will the chemical equilibrium shift? need more information to be determined at equilibrium chemical equilibrium will shift to the right first and then to the left chemical equilibrium will shift to the right chemical equilibrium will shift to the left 201591..docx LAB EXP. #3 -..docx Show AllThe concentration of Ba(103)2 in H20 at 35°C (Ksp = 3.00 x 10-9 ) Ba(103)2 (s) - Ba2+ +2103 O 5.23 x 10-4 M 6.69x104 M O 2.37 x 104 M O 7.32 x 10-4 M 9.09 x10 4 M
