) Listen The Kep value for calcium sulfate [CaSO4) is 2.40 X 10-5 and a professor made 1825 mL of a CaSO4lag) 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. Calculate the new equilibrium constant (K) with this common ion effect. 1.20 x 10-5 3.44 x 10-5 3.84 x 10-5 2.01 x 10-5 O 1.48 x 10-5 1591....docx LAB EXP, #3 -.docx Show All
